Is predicted to encode a protein with the following domains: Diacylglycerol/phorbol-ester binding; Phorbol esters/diacylglycerol binding domain (C1 domain); Protein kinase-like domain superfamily; and Protein kinase C-like, phorbol ester/diacylglycerol-binding domain. Is an ortholog of C. elegans tpa-1. In C. elegans, tpa-1 is involved in several processes, including defense response to other organism; peptidyl-serine phosphorylation; and positive regulation of antimicrobial peptide production.
