Enables integrin binding activity and metalloendopeptidase inhibitor activity. Involved in several processes, including positive regulation of adenylate cyclase activity; positive regulation of neuron differentiation; and regulation of intracellular signal transduction. Located in several cellular components, including cell surface; growth cone; and neuronal cell body. Used to study portal hypertension. Biomarker of cardiomyopathy; congestive heart failure; and intracranial aneurysm. Human ortholog(s) of this gene implicated in Moyamoya disease. Orthologous to human TIMP2 (TIMP metallopeptidase inhibitor 2). [provided by Alliance of Genome Resources, Apr 2022]
