Enables protein serine/threonine kinase activity. Acts upstream of or within several processes, including cellular response to UV; negative regulation of protein metabolic process; and negative regulation of stress-activated MAPK cascade. Predicted to be located in nucleus. Is expressed in several s
tructures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human PBK (PDZ binding kinase). [provided by Alliance of Genome Resources, Jul 2025]
Predicted to enable mRNA 3'-UTR binding activity and mRNA 5'-UTR binding activity. Predicted to be involved in regulation of apoptotic process and regulation of cellular senescence. Predicted to act upstream of or within regulation of protein localization. Located in nucleolus. Is expressed in sever
al structures, including eye; genitourinary system; liver; lung; and spleen. Orthologous to human RSL1D1 (ribosomal L1 domain containing 1). [provided by Alliance of Genome Resources, Jul 2025]
