Enables protein kinase activity. Acts upstream of or within several processes, including parturition; positive regulation of JNK cascade; and regulation of spongiotrophoblast cell proliferation. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; limb; and musculature. Orthologous to human NRK (Nik related kinase). [provided by Alliance of Genome Resources, Apr 2022]
