Encyclopedia > List of gene families

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. A gene family is a set of genes defined by presumed homology, i. ... A gene complex is a set of genes that perform similar roles in a biological function. ... In biology, a species is a kind of organism. ...

Genes-encoding regulatory proteins

  • Homeobox (Hox gene family)
  • Achaete-scute complex (Neuroblast formation)

A homeobox is a stretch of DNA sequence found in genes involved in the regulation of the development (morphogenesis) of animals, fungi and plants. ... A neuroblast is a dividing cell that will develop into neurons or glia. ...

Genes-encoding immune system proteins

The major histocompatibility complex (MHC) is a large genomic region or gene family found in most vertebrates containing many genes with important immune system roles. ...

Gene family - Wikipedia, the free encyclopedia (195 words)
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.
