Calca Gene Summary [Rat]
Predicted to enable calcitonin receptor binding activity; hormone activity; and identical protein binding activity. Involved in several processes, including cellular response to nerve growth factor stimulus; cellular response to tumor necrosis factor; and vasodilation. Located in axon; extracellular space; and neuronal cell body. Is active in hippocampal mossy fiber to CA3 synapse and neuronal dense core vesicle. Used to study acute necrotizing pancreatitis; ischemia; and stomach disease. Biomarker of middle cerebral artery infarction; migraine; prediabetes syndrome; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in migraine and osteoporosis. Orthologous to human CALCA (calcitonin related polypeptide alpha). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Calca often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
