UniProt functional annotation for P62152

UniProt code: P62152.

Organism: Drosophila melanogaster (Fruit fly).
Taxonomy: Eukaryota; Metazoa; Ecdysozoa; Arthropoda; Hexapoda; Insecta; Pterygota; Neoptera; Endopterygota; Diptera; Brachycera; Muscomorpha; Ephydroidea; Drosophilidae; Drosophila; Sophophora.
 
Function: Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+) (By similarity). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases (By similarity). In photoreceptor cells, light-induced Ca(2+) influx activates calmodulin, which in turn is likely to promote Crag activity in trafficking of newly synthesized ninaE (Rh1) from the trans-Golgi network to rhabdomere membranes (PubMed:23226104). Together with Akap200, regulates PKA activity and ethanol-induced sensitivity and tolerance (PubMed:10480937, PubMed:29444420). {ECO:0000250|UniProtKB:P02599, ECO:0000269|PubMed:10480937, ECO:0000269|PubMed:23226104, ECO:0000269|PubMed:29444420}.
 
Subunit: Interacts with Crag (PubMed:18331716). Interacts with stac (PubMed:9813038). Interacts with Akap200; the interaction is calcium- dependent and is inhibited by PKC-mediated phosphorylation of Akap200 (PubMed:10480937). {ECO:0000269|PubMed:10480937, ECO:0000269|PubMed:18331716, ECO:0000269|PubMed:9813038}.
Subcellular location: Cytoplasm, cell cortex {ECO:0000269|PubMed:18331716}.
Ptm: Trimethylation of Lys-116 observed in other calmodulins is absent here, but does occur at Lys-95 specifically in the compound eye.
Disruption phenotype: RNAi-mediated knockdown in the perineurial glia increases ethanol sedation resistance and decreases ethanol tolerance. {ECO:0000269|PubMed:29444420}.
Miscellaneous: This protein has four functional calcium-binding sites.
Miscellaneous: Two alternative gene models exist that generate identical translations.
Similarity: Belongs to the calmodulin family. {ECO:0000305}.
