PSPC1 Polyclonal Antibody

function:Regulates, cooperatively with NONO and SFPQ, androgen receptor-mediated gene transcription activity in Sertoli cell line (By similarity). Binds to poly(A), poly(G) and poly(U) RNA homopolymers.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,sequence caution:Translated as Lys.,similarity:Belongs to the PSPC family.,similarity:Contains 2 RRM (RNA recognition motif) domains.,subcellular location:In punctate subnuclear structures often located adjacent to splicing speckles, called paraspeckles. Colocalizes with NONO and SFPQ in paraspeckles and perinucleolar caps in a RNA-dependent manner. May cycles between paraspeckles and nucleolus. In telophase, when daughter nuclei form, localizes to perinucleolar caps.,subunit:Forms heterodimers with NONO. Found in a RNP complex with CAT2 transcribed nuclear RNA (CTN-RNA). Interaction with NONO is required for its targeting to paraspeckles and perinucleolar caps. Interacts with SFPQ.,tissue specificity:Expressed in pancreas, kidney, skeletal muscle, liver, lung, placenta, brain and heart.,
