Cacna1b Gene Summary [Rat]

Enables high voltage-gated calcium channel activity; protein phosphatase 2A binding activity; and voltage-gated calcium channel activity involved in regulation of presynaptic cytosolic calcium levels. Involved in several processes, including calcium ion import; regulation of calcium-dependent activation of synaptic vesicle fusion; and response to phorbol 13-acetate 12-myristate. Located in axon terminus; dendritic shaft; and neuronal cell body. Part of protein-containing complex. Is active in Schaffer collateral - CA1 synapse and glutamatergic synapse. Human ortholog(s) of this gene implicated in Lambert-Eaton myasthenic syndrome. Orthologous to human CACNA1B (calcium voltage-gated channel subunit alpha1 B).

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 Cacna1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
