Enables calmodulin-dependent protein kinase activity; identical protein binding activity; and transmembrane transporter binding activity. Involved in MAPK cascade; medium-term memory; and positive regulation of gene expression. Acts upstream of or within serotonin biosynthetic process. Located in axon cytoplasm. Expressed in several structures, including AWC; copulatory spicule; gonadal sheath cell; oocyte; and somatic nervous system. Human ortholog(s) of this gene implicated in Alzheimer's disease; intellectual disability (multiple); and malignant astrocytoma. Is an ortholog of human CAMK2D (calcium/calmodulin dependent protein kinase II delta).
Expressed in body wall musculature; germ line; hypodermis; intestine; and pharynx. Is predicted to encode a protein with the following domains: Phosducin, N-terminal domain superfamily; Phosducin; Thioredoxin-like superfamily; and Phosducin, thioredoxin-like domain. Is an ortholog of human PDC (phosducin) and PDCL (phosducin like).
