Chp1 Gene Summary [Rat]
Enables calcium ion binding activity; kinase binding activity; and microtubule binding activity. Involved in several processes, including microtubule cytoskeleton organization; protein export from nucleus; and regulation of protein modification process. Located in several cellular components, including Golgi membrane; endoplasmic reticulum; and transport vesicle. Human ortholog(s) of this gene implicated in spastic ataxia. Orthologous to human CHP1 (calcineurin like EF-hand protein 1). [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 Chp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
