Protocadherin alpha-9 is a protein that in humans is encoded by the PCDHA9 gene.This gene is a member of the protocadherin alpha gene cluster one of three related gene clusters tandemly linked on chromosome 5 that demonstrate an unusual genomic organization similar to that of B-cell and T-cell receptor gene clusters. The alpha gene cluster is composed of 15 cadherin superfamily genes related to the mouse CNR genes and consists of 13 highly similar and 2 more distantly related coding sequences.
