Summary
Enables calcium/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. Is expressed in several structures, including copulatory spicule; gonadal sheath cell; nervous system; oocyte; and postcloacal sensillum. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 53; autosomal dominant intellectual developmental disorder 54; autosomal dominant intellectual developmental disorder 59; and autosomal recessive intellectual developmental disorder 63. Orthologous to several human genes including CAMK2D (calcium/calmodulin dependent protein kinase II delta). [provided by Alliance of Genome Resources, Jul 2025]
