Summary: Enables protein serine/threonine kinase activity. Involved in several processes, including cell integrity MAPK cascade; late endosome to vacuole transport via multivesicular body sorting pathway; and positive regulation of cytoplasmic mRNA processing body assembly. Located in cell cortex and nucleus. Human ortholog(s) of this gene implicated in prostate cancer. Orthologous to human PDPK1 (3-phosphoinositide dependent protein kinase 1) and PDPK2P (3-phosphoinositide dependent protein kinase 2, pseudogene). [provided by Alliance of Genome Resources, Nov 2024]
