Is an ortholog of human CPN1 (carboxypeptidase N subunit 1). Exhibits carboxypeptidase activity. Is involved in several processes, including acetylcholine secretion, neurotransmission; cellular response to carbon dioxide; and positive regulation of secretion. Localizes to axon; cytoplasmic vesicle; and neuronal cell body. Is expressed in nerve ring; neurons; and preanal ganglion. Human ortholog(s) of this gene are implicated in carboxypeptidase N deficiency.
Is an ortholog of human INSM1 (INSM transcriptional repressor 1) and INSM2 (INSM transcriptional repressor 2). Exhibits RNA polymerase II transcription factor binding activity. Is involved in cell fate commitment; generation of neurons; and positive regulation of exit from mitosis. Localizes to nucleus. Is expressed in several structures, including QL.aa; QL.pp; QR.aa; QR.pp; and neurons.
