Protocadherin-15 is a protein that in humans is encoded by the PCDH15 gene.[3][4][5]

Function[edit]

This gene is a member of the cadherin superfamily. Family members encode integral membrane proteins that mediate calcium-dependent cell-cell adhesion. The protein product of this gene consists of a signal peptide, 11 extracellular calcium-binding domains, a transmembrane domain and a unique cytoplasmic domain. It plays an essential role in maintenance of normal retinal and cochlear function.[5] It is thought to interact with CDH23 to form tip-link filaments.[6]

Clinical significance[edit]

Mutations in this gene have been associated with hearing loss, which is consistent with its location at the Usher syndrome type 1F (USH1F) critical region on chromosome 10.[5]
