GJA8 gap junction protein alpha 8

Gene ID: 2703, updated on 2-Nov-2024
Gene type: protein coding
Also known as: CAE; CAE1; CX50; CZP1; MP70; CTRCT1

Summary

This gene encodes a transmembrane connexin protein that is necessary for lens growth and maturation of lens fiber cells. The encoded protein is a component of gap junction channels and functions in a calcium and pH-dependent manner. Mutations in this gene have been associated with zonular pulverulent cataracts, nuclear progressive cataracts, and cataract-microcornea syndrome. [provided by RefSeq, Dec 2009]
