Enables several functions, including ATP binding activity; SH2 domain binding activity; and magnesium ion binding activity. Involved in several processes, including intracellular signal transduction; negative regulation of Wnt signaling pathway; and protein phosphorylation. Acts upstream of or within protein autophosphorylation. Located in nucleus. Is expressed in several structures, including early embryo; genitourinary system; nervous system; neural retina; and respiratory system. Orthologous to human NLK (nemo like kinase).
