Exhibits cysteine-type endopeptidase inhibitor activity involved in apoptotic process and mitogen-activated protein kinase kinase binding activity. Involved in several processes, including positive regulation of insulin secretion involved in cellular response to glucose stimulus; regulation of cellular protein metabolic process; and regulation of signal transduction. Localizes to cytosol and pseudopodium. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; liver; and respiratory system. Orthologous to human ARRB1 (arrestin beta 1).
