Function: May play a role in mRNA splicing. May also bind to DNA.
Subunit: Identified in the spliceosome C complex. Part of a tri-snRNP complex.
Subcellular Location: Nucleus. Note=Found in the nucleus of mitogen-activated peripheral blood mononuclear cells (PBMCs), tumor cells, or normal cell lines, but not in normal tissues except testis and fetal liver or in unstimulated PBMCs, suggesting preferential expression in proliferating cells.
