Enables calmodulin binding activity. Predicted to be involved in several processes, including calmodulin dependent kinase signaling pathway; negative regulation of protein kinase activity; and positive regulation of dopamine secretion. Predicted to be located in axon and neurofilament. Predicted to be part of protein-containing complex. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; peripheral nervous system; and sensory organ. Orthologous to human PCP4 (Purkinje cell protein 4). [provided by Alliance of Genome Resources, Apr 2022]
