Homeobox protein Hox-A13 is a protein that in humans is encoded by the HOXA13 gene. [5] [6] [7]

Contents

Function

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

Expansion of a polyalanine tract in the encoded protein can cause hand-foot-genital syndrome, also known as hand-foot-uterus syndrome. [8] Aberrant expression of HoxA13 gene products in the esophagus, provokes Barrett’s esophagus, a form of metaplasia that is a direct precursor to esophageal cancer. [9]
