About KRT4

Cytogenetic location: 12q13.13 Genomic coordinates (GRCh38): 12:52,806,549-52,814,116 (from NCBI)

This gene has 5 transcripts (splice variants), 96 orthologues, 68 paralogues and is associated with 3 phenotypes. Restricted expression toward esophagus (RPKM 10134.3).

Summary

The protein encoded by this gene is a member of the keratin gene family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in differentiated layers of the mucosal and esophageal epithelia with family member KRT13. Mutations in these genes have been associated with White Sponge Nevus, characterized by oral, esophageal, and anal leukoplakia. The type II cytokeratins are clustered in a region of chromosome 12q12-q13. [provided by RefSeq, Jul 2008]
