Previous Symbols for CALCA Gene
This gene encodes the peptide hormones calcitonin, calcitonin gene-related peptide and katacalcin by tissue-specific alternative RNA splicing of the gene transcripts and cleavage of inactive precursor proteins. Calcitonin is involved in calcium regulation and acts to regulate phosphorus metabolism. Calcitonin gene-related peptide functions as a vasodilator and as an antimicrobial peptide while katacalcin is a calcium-lowering peptide. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2014]
GeneCards Summary for CALCA Gene
CALCA (Calcitonin-Related Polypeptide Alpha) is a Protein Coding gene. Diseases associated with CALCA include paroxysmal hemicrania and discitis. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include identical protein binding and protein complex binding. An important paralog of this gene is CALCB.
CGRP induces vasodilation. It dilates a variety of vessels including the coronary, cerebral and systemic vasculature. Its abundance in the CNS also points toward a neurotransmitter or neuromodulator role. It also elevates platelet cAMP.
Calcitonin causes a rapid but short-lived drop in the level of calcium and phosphate in blood by promoting the incorporation of those ions in the bones
Katacalcin is a potent plasma calcium-lowering peptide
