Protein-coding gene in the species Homo sapiens
Protocadherin-18 is a protein that in humans is encoded by the PCDH18 gene.[5][6][7]
This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. This gene encodes a protein which contains 6 extracellular cadherin domains, a transmembrane domain and a cytoplasmic tail differing from those of the classical cadherins. Although its specific function is undetermined, the cadherin-related neuronal receptor is thought to play a role in the establishment and function of specific cell-cell connections in the brain.[7]
