Predicted to contribute to tRNA (guanine-N7-)-methyltransferase activity. Predicted to be involved in tRNA modification. Predicted to act upstream of or within cellular response to DNA damage stimulus and tRNA processing. Predicted to be located in nucleoplasm. Predicted to be part of tRNA methyltransferase complex. Predicted to be active in cytosol and nucleus. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; sensory organ; and thymus. Human ortholog(s) of this gene implicated in Galloway-Mowat syndrome. Orthologous to human WDR4 (WD repeat domain 4). [provided by Alliance of Genome Resources, Apr 2022]
