Enables protein serine/threonine kinase activity. Involved in several processes, including positive regulation of cellular component biogenesis; positive regulation of protein transport; and response to glucose. Located in several cellular components, including neuromuscular junction; nucleus; and sarcolemma. Biomarker of hyperinsulinism and prostate adenocarcinoma. Orthologous to human PRKCQ (protein kinase C theta). [provided by Alliance of Genome Resources, Apr 2022]
