Calcitonin gene-related peptide 1

Gene

CALCA

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.1 Publication

Isoform 1 (identifier: P01258-1) [UniParc]FASTAAdd to basket
The sequence of this isoform can be found in the external entry P01258.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.

Isoform 2 (identifier: P01258-2) [UniParc]FASTAAdd to basket
The sequence of this isoform can be found in the external entry P01258.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.
Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.
