CC -!- FUNCTION: Calcium/calmodulin-dependent protein kinase which
CC phosphorylates cmk-1 (PubMed:10336483, PubMed:10428833,
CC PubMed:12231504). Component of a calcium-triggered signaling cascade
CC involved in CRE-mediated transcriptional activation, probably through
CC cmk-1-mediated crh-1/CREB phosphorylation (PubMed:12231504).

CC -!- TISSUE SPECIFICITY: Expressed in head and tail neurons and vulval
CC muscles. {ECO:0000269|PubMed:12231504}.
CC -!- DOMAIN: The autoinhibitory domain overlaps with the calmodulin binding
CC region and may be involved in intrasteric autoinhibition.
CC {ECO:0000250|UniProtKB:P97756}.
CC -!- DOMAIN: The RP domain (arginine/proline-rich) is involved in the
CC recognition of substrates such as cmk-1.
CC {ECO:0000250|UniProtKB:P97756}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. {ECO:0000255|PROSITE-ProRule:PRU00159}.
