FunShift: Database of Pfam Subfamilies and Functional Shift Analysis It is compilation of subfamilies derived from Pfam domain family database and the analysis of these subfamilies for functional conservation or divergence (functional shift). Subfamilies are frequently representative of sets of proteins with related functions and/or distinct domain organizations resulting from different evolution histories with in a Family. Function shift between a subfamily pair was predicted by using the percentage of CSS and RSS as variables in classification functions. funshift.cgb.ki.se /faq.html   (869 words)

[No title]   (Site not responding. Last check: ) We interpret the branching pattern as clustering into at least six subfamilies, designated A-F. The presence of highly similar elements within the B, C, D, and F subfamilies is evidence that a distinct progenitor has spawned each of these subfamilies. The nucleotide divergence between members of subfamily C was 5%-8%, suggesting that this subfamily has undergone a relatively recent burst of retrotransposition. The A and E subfamilies may have been spawned from ancestors of these four progenitors or from other, distinct progenitors. www.mnhn.fr /mnhn/oseb/these/resumes/vandergon.html   (244 words)

RedNova News - Science - Phylogeny and Divergence-Date Estimates of Rapid Radiations in Muroid Rodents Based on ...   (Site not responding. Last check: ) Systematists have generally agreed on the composition of the subfamilies and to a certain extent on the number of the subfamilies, between 16 and 20. They found that the mole-rat subfamilies (Spalacinae and Rhizomyinae) were the sister group to all other muroids, but they were unable to resolve the branching pattern, among most of the remaining subfamilies and speculated that robust resolution may never be achieved. In all but four subfamilies, alternate topologies wherein they were not monophyletic could be rejected under either one or both optimality criteria at the 0.05 level (after Bonferroni correction to 0.0015 for Kishino-Hasegawa and Templeton's test). www.rednova.com /news/display?id=92552   (9123 words)

Diversity, taxonomy and evolution of medium-chain dehydrogenase/reductase superfamily -- Riveros-Rosas et al. 270 (16): ...   (Site not responding. Last check: ) Subfamilies present only in one kingdom are indicated in italics: bacteria or archaea; normal type indicates subfamilies present in two or more kingdoms. Subfamilies with restricted distribution are shown in italics, with subfamilies with broad distribution shown in normal font. Identification of protein subfamilies as nonoverlapping clusters (closed groups) is advantageous over distance-based clustering methods because it is not necessary to set an arbitrary identity cutoff value, and permits the identification of both highly and poorly conserved groups of orthologous proteins. content.febsjournal.org /cgi/content/full/270/16/3309   (8680 words)

Mosaic Structure and Retropositional Dynamics During Evolution of Subfamilies of Short Interspersed Elements in African ... ) of the consensus sequences of the subfamilies Subfamilies of sequences are identified by differently colored backgrounds. Polytomies in the tree indicate the absence of a sufficient number of informative loci to support the corresponding relationships or the existence of incongruities with respect to patterns of insertion of SINEs among loci, possibly as a result of incomplete lineage sorting or interspecific hybridization (Takahashi et al. mbe.oxfordjournals.org /cgi/content/full/19/8/1303   (4936 words)

Whole-genome analysis of Alu repeat elements reveals complex evolutionary history -- Price et al. 14 (11): 2245 -- ... Small subfamilies nested inside large subfamilies, a typical scenario in Alu repeat subfamilies, are not easily identified, because there is a tendency to split off a larger cluster (B) instead of identifying the nested subfamily (C). A timeline roughly depicting the average divergence of each subfamily from its consensus sequence and the approximate age obtained by applying a constant scaling factor of 4 million years per 1% divergence from consensus sequence are included at right.

SUBFAMILIES HYDROBATINAE AND OCEANITINAE WITHIN THE FAMILY HYDROBATINAE Many classifications (e.g., Carboneras 1992c) divide the family into two subfamilies, Hydrobatinae and Oceanitinae, but this classification follows the AOU (1998) in not recognizing these until corroborated by multiple independent data sets that mark major, deep branches within the family. This provides strong support for the division of the Hydrobatidae into two subfamilies: Oceanitinae, comprising taxa from Oceanites oceanica to Fregetta tropica; and Hydrobatinae, with taxa from Hydrobates pelagicus to Oceanodroma castro. That the subfamilies Oceanitinae and Hydrobatinae be recognized with the family Hydrobatidae. www.museum.lsu.edu /~Remsen/SACCprop167.html   (495 words)

Australian River Assessment System: AusRivAS Protocols Development and Testing Report: Results (continued)   (Site not responding. Last check: ) For Queensland sites there was a distinct relationship between the number of chironomids picked from a sample and the number of chironomid subfamilies identified in the sample (Figure 9). Only one extra subfamily, Podonominae, was recorded and this occurred in a single edge habitat sample from an upland site from which 64 chironomids were collected using the minimum number of animals pick protocol. No extra subfamilies were collected in the extra 15 minutes of picking from any sample. www.deh.gov.au /water/rivers/nrhp/test/chapter4b.html   (402 words)

Guide to the Genera of New World Pleurostict Scarab Beetles   (Site not responding. Last check: ) The hierarchical level of families and subfamilies within the Scarabaeoidea is in disarray and remains unresolved. Whereas families, subfamilies, and tribes in the staphylinoids and curculionoids are being combined because of shared characters (thus increasing efficient data retrieval), the scarabaeoids are being split into numerous families because of supposed differences (thus, in our view, decreasing information retrieval). The position of the spiracles, however, is not a consistent character (Ritcher 1969), and, in recent years, subfamilies and tribes that were once included in the Laparosticti have been raised to higher taxonomic status (family and subfamily, respectively). www-museum.unl.edu /research/entomology/Guide/Scarabaeoidea/ScarabaeoideaO.htm   (2302 words)

Untitled Document It can be hypothesised that if these subfamilies vary in their sensitivity to stimuli for performing specific tasks, such as fanning, this might result in some subfamilies carrying out those tasks more often than other subfamilies. Therefore it can be hypothesised that more genetically diverse colonies are more likely to accurately regulate the temperature in the hive than colonies with fewer subfamilies because they would have a larger distribution of temperature thresholds at which they would act to regulate brood nest temperature. In addition there was a significant difference between overall subfamily proportions in the colony and the proportion of subfamilies fanning at different temperatures. www.bio.usyd.edu.au /Social_InsectsLab/Julia/Julia.htm   (356 words)

Large-scale evaluation and prediction of function shift in protein families The methodology was evaluated in a large-scale test based on the Pfam database, from which we derived subfamilies with either the same or different EC numbers. Subfamilies were derived using the BETE method, which resulted in 997 subfamily pairs with four or more members per subfamily. We tested the hypothesis that the more CS and RS sites between two subfamilies, the more likely a functional shift between them is. The results showed a significant increase in CS and RS sites for subfamily comparisons with different EC numbers compared to cases with same EC numbers. www.iscb.org /ismb2004/posters/abhiman.saraswathiATcgb.ki.se_277.html   (685 words)

PANTHER - Classifications of Genes and Proteins The PANTHER (Protein ANalysis THrough Evolutionary Relationships) Classification System is a unique resource that classifies genes by their functions, using published scientific experimental evidence and evolutionary relationships to predict function even in the absence of direct experimental evidence. Proteins are classified by expert biologists into families and subfamilies of shared function, which are then categorized by molecular function and biological process ontology terms. For an increasing number of proteins, detailed biochemical interactions in canonical pathways are captured and can be viewed interactively. www.pantherdb.org   (242 words)
