Enables alpha-tubulin binding activity. Acts upstream of or within several processes, including chaperone cofactor-dependent protein refolding; negative regulation of intracellular signal transduction; and positive regulation of nitrogen compound metabolic process. Located in cytoplasm and nucleus. Colocalizes with microtubule. Is expressed in several structures, including brain; gut; integumental system; liver and biliary system; and reproductive system. Orthologous to human HSPH1 (heat shock protein family H (Hsp110) member 1). [provided by Alliance of Genome Resources, Apr 2022]
