Enables U6 snRNA binding activity. Involved in ncRNA metabolic process; regulation of mRNA splicing, via spliceosome; and spermatogenesis. Acts upstream of or within several processes, including germ cell proliferation; negative regulation of chromatin binding activity; and positive regulation of G1/S transition of mitotic cell cycle. Located in nucleus. Is expressed in several structures, including central nervous system; gonad; liver; sensory organ; and spleen. Orthologous to human LARP7 (La ribonucleoprotein 7, transcriptional regulator). [provided by Alliance of Genome Resources, Apr 2022]
