Enables diazepam binding activity. Involved in several processes, including postsynapse to nucleus signaling pathway; regulation of cAMP-dependent protein kinase activity; and regulation of protein localization to nucleus. Acts upstream of or within several processes, including carboxylic acid metabolic process; positive regulation of cilium assembly; and transport along microtubule. Located in several cellular components, including centriole; inclusion body; and perinuclear region of cytoplasm. Is active in glutamatergic synapse. Is expressed in several structures, including central nervous system; olfactory epithelium; peripheral nervous system; retina; and testis. Used to study Huntington's disease. Human ortholog(s) of this gene implicated in Huntington's disease and Parkinson's disease. Orthologous to human HTT (huntingtin). [provided by Alliance of Genome Resources, Apr 2022]
