Protocadherin gamma-B7 is a protein that in humans is encoded by the PCDHGB7 gene.{{cite journal | vauthors = Wu Q, Maniatis T | title = A striking organization of a large family of human neural cadherin-like cell adhesion genes | journal = Cell | volume = 97 | issue = 6 | pages = 779–90 |date=Jul 1999 | pmid = 10380929 | doi =10.1016/S0092-8674(00)80789-8 | s2cid = 6014717 | doi-access = free }}{{cite web | title = Entrez Gene: PCDHGB7 protocadherin gamma subfamily B, 7| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=56099}}
This gene is a member of the protocadherin gamma gene cluster, one of three related clusters tandemly linked on chromosome five. These gene clusters have an immunoglobulin-like organization, suggesting that a novel mechanism may be involved in their regulation and expression. The gamma gene cluster includes 22 genes divided into 3 subfamilies. Subfamily A contains 12 genes, subfamily B contains 7 genes and 2 pseudogenes, and the more distantly related subfamily C contains 3 genes. The tandem array of 22 large, variable region exons are followed by a constant region, containing 3 exons shared by all genes in the cluster. Each variable region exon encodes the extracellular region, which includes 6 cadherin ectodomains and a transmembrane region. The constant region exons encode the common cytoplasmic region. These neural cadherin-like cell adhesion proteins most likely play a critical role in the establishment and function of specific cell-cell connections in the brain. Alternative splicing has been described for the gamma cluster genes.
