CC -!- FUNCTION: Functions as a modulator of calcium-binding by calmodulin.
CC Thereby, regulates calmodulin activity and the different processes it
CC controls. For instance, may play a role in neuronal differentiation
CC through activation of calmodulin-dependent kinase signaling pathways.
CC {ECO:0000250|UniProtKB:P48539}.
CC -!- SUBUNIT: Binds to both calcium-free and calcium-bound calmodulin. The
CC affinity for the calcium-bound form is 50-fold greater.
CC {ECO:0000250|UniProtKB:P48539}.
CC -!- TISSUE SPECIFICITY: Restricted to the nervous system. Expressed
CC throughout the brain, in particular forebrain regions, including the
CC granular layer of the olfactory bulb, and pyriform cortex. Also
CC expressed in the hippocampus, caudate putamen and the cerebellum, where
CC it is associated predominantly with Purkinje cells.
CC {ECO:0000269|PubMed:2748608}.
CC -!- DEVELOPMENTAL STAGE: Detectable in the brain at embryonic day 17. The
CC levels increase to reach a maximal value at postnatal day 18.
CC {ECO:0000269|PubMed:2748608}.
CC -!- DOMAIN: Mostly intrinsically disordered, with residual structure
CC localized to the IQ domain which mediates the interaction with
CC calmodulin. {ECO:0000250|UniProtKB:P48539}.
CC -!- SIMILARITY: Belongs to the PCP4 family. {ECO:0000305}.
