Enables serine-type endopeptidase activity. Involved in several processes, including positive regulation of cell migration; positive regulation of transforming growth factor beta receptor signaling pathway; and protein processing. Located in Golgi cisterna; endoplasmic reticulum membrane; and plasma membrane. Orthologous to human FURIN (furin, paired basic amino acid cleaving enzyme).
