Predicted to enable protein serine/threonine phosphatase inhibitor activity. Predicted to be involved in regulation of phosphorylation. Predicted to be located in cytoplasm. Is expressed in several structures, including embryonic brain; embryonic central brain neurons; gut section; larval muscle cell; and sensory nervous system primordium. Orthologous to several human genes including PPP1R14B (protein phosphatase 1 regulatory inhibitor subunit 14B).
