Predicted to enable beta-catenin binding activity and histone methyltransferase activity (H3-K4 specific). Involved in several processes, including histone H3-K4 methylation; regulation of chromatin organization; and regulation of erythrocyte differentiation. Acts upstream of or within positive regulation of neural precursor cell proliferation; positive regulation of stem cell proliferation; and stem cell population maintenance. Located in euchromatin and nucleus. Is expressed in several structures, including early conceptus; integumental system; liver; nervous system; and oocyte. Orthologous to human SETD1A (SET domain containing 1A, histone lysine methyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
