Predicted to enable peptide binding activity and serine-type endopeptidase activity. Involved in several processes, including cellular response to platelet-derived growth factor stimulus; positive regulation of integrin-mediated signaling pathway; and positive regulation of smooth muscle cell-matrix adhesion. Located in several cellular components, including Golgi apparatus subcompartment; perikaryon; and proximal dendrite. Biomarker of sciatic neuropathy. Orthologous to human PCSK5 (proprotein convertase subtilisin/kexin type 5). [provided by Alliance of Genome Resources, Apr 2022]
