Protein-coding gene in the species Homo sapiens
Homeobox protein Hox-A13 is a protein that in humans is encoded by the HOXA13 gene .[5] [6] [7]
Function [ edit ] In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development . This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression , morphogenesis , and differentiation .[7]
Clinical significance [ edit ] Expansion of a polyalanine tract in the encoded protein can cause hand-foot-genital syndrome , also known as hand-foot-uterus syndrome.[8] HoxA13 gene products in the esophagus , provokes Barrett’s esophagus , a form of metaplasia that is a direct precursor to esophageal cancer .[9]
