PCP4

Protein-coding gene in the species Homo sapiens

Purkinje cell protein 4 is a protein that in humans is encoded by the PCP4 gene.[5][6][7] Also known as PEP-19, PCP4 is a 7.6 kDa protein with an IQ-motif that binds to calmodulin (CaM).[8] PCP4 is abundant in Purkinje cells of the cerebellum, and plays an important role in synaptic plasticity.[8][9]

Function

PCP4 knockout mice have been reported to exhibit impaired locomotor learning and markedly altered synaptic plasticity in cerebellar Purkinje neurons.[8] PCP4 accelerates both the association and dissociation of calcium (Ca2+) with calmodulin (CaM), which is postulated to influence the activity of CaM-dependent enzymes, especially CaM kinase II (CaMK-II).[8][10][11]
