The function of ENSG00000183036 (PCP4, Purkinje cell protein 4) is as follows. Functions as a modulator of calcium-binding by calmodulin. Thereby, regulates calmodulin activity and the different processes it controls (PubMed:19106096, PubMed:23204517, PubMed:27876793). For instance, may play a role in neuronal differentiation through activation of calmodulin-dependent kinase signaling pathways (PubMed:21491429). {ECO:0000269|PubMed:19106096, ECO:0000269|PubMed:21491429, ECO:0000269|PubMed:23204517, ECO:0000269|PubMed:27876793}.
