Predicted to enable ATP binding activity and diacylglycerol-dependent serine/threonine kinase activity. Predicted to be involved in protein phosphorylation. 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.
