an ortholog of calcium-dependent serine endoproteinases, the kex2/subtilisin-like proprotein convertase that affects defecation cycle and anterior body contractions; and is expressed in all muscle cells except pharyngeal muscles.
Enables serine-type endopeptidase activity. Involved in several processes, including neuropeptide processing; positive regulation of synaptic assembly at neuromuscular junction; and positive regulation of transport. Located in extracellular space.
