  Gene   (Site not responding. Last check: 2007-11-06)
Because it is through proteins that genes exert their effects, and because gene transcripts (which are a prerequisite for protein synthesis) degrade rapidly, genes are in a sense inactive when they are not actively being transcribed.
In common speech, "gene" is often used to refer to the hereditary cause of a trait, disease or condition--as in "the gene for obesity." A biologist, in contrast, might refer to an allele or a mutation that had been implicated in or correlated with obesity.
For various reasons, the relationship between genes and proteins is not so simple as "one nucleotide sequence-->one amino-acid sequence." For example, cells may splice the transcripts of a gene in alternate ways to produce not one but a variety of proteins (alternative splicing).

 Gene family - Wikipedia, the free encyclopedia
A gene family is a set of genes defined by presumed homology, i.e.
Genes are generally categorized into families based upon shared sequence motifs and similarities in structure.
If the genes of a gene family encode proteins, the term protein family is often used in an analogous manner to gene family.

 List of gene families - Wikipedia, the free encyclopedia
This is a list of gene families or gene complexes, that is sets of genes which occur across a number of different species which often serve similar biological functions.
These gene families typically encode functionally related proteins, and sometimes the term gene families is a shorthand for the sets of proteins that the genes encode.
They may or may not be physically adjacent on the same chromosome.

 Gene definitions
Genes reside within one another, share some of their DNA sequences, are transcribed and spliced in complex patterns, and can overlap in function with other genes of the same sequence families.
In eukaryotes, genes are not clustered in operons.
Gene superfamily is defined as "a cluster of evolutionarily related sequences" (Dayhoff, 1976), and consists of homologous gene families, which are clusters of genes from different genomes that include both orthologs and paralogs (Tatusov et al., 1997).

 Drosophila gene families: Proneural and neurogenic genes   (Site not responding. Last check: 2007-11-06)
These genes are termed proneural, since they promote neuroblast differentiation and are thus essential for the differentiation of the central and peripheral nervous system and the brain.
AS-C genes are activated in proneural clusters in the ventral portion of the fly.
Gene regulation in two dimensions: the proneural achaete and scute genes are controlled by combinations of axis-patterning genes through a common intergenic control region.

 Genome Biology | Full text | Identification of conserved C2H2 zinc-finger gene families in the Bilateria
Implicit in such extrapolations is that the genes being compared are orthologous, that is, they derive from the same ancestral gene in the common ancestor of the model organism and humans [1].
Such an exercise essentially reconstructs the minimum gene complement, for a particular superfamily, that would have been present in the last common ancestor of these three taxa and, given their phylogenetic relationship [4], gives insight into the genome complexity of the bilaterian common ancestor.
With these analyses we defined a total of 39 families of genes (Table 1) which we propose represent 'orthology groups', as we infer that each group is descended from a single ancestral gene in the most recent common ancestor of Drosophila, C. elegans and humans.

The genes are placed in one of three groups: Putative genes with good to exact hits to sequences of known function, Predicted genes which are identical to an EST yet have no ascribed function, and Hypothetical genes which have no database match.
The Gene Family heading in the first table below serves as a label for that group of sequences and may be linked to a type of review of those sequences.
If a gene is known to exhibit more than one function or is known to affect a second cellular process, that gene is listed under more than one Gene Family.
