Enables calcium ion binding activity; kinase binding activity; and microtubule binding activity. Involved in several processes, including microtubule cytoskeleton organization; protein stabilization; and regulation of protein modification process. Located in several cellular components, including Golgi membrane; microtubule cytoskeleton; 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, Apr 2022]
