Protein Structure
UniProt Annotation
Function Together with NONO, required for the formation of nuclear paraspeckles. Regulates, cooperatively with NONO and SFPQ, androgen receptor-mediated gene transcription activity in Sertoli cell line. Binds to poly(A), poly(G) and poly(U) RNA homopolymers. Regulates the circadian clock by repressing the transcriptional activator activity of the CLOCK-ARNTL/BMAL1 heterodimer (By similarity). {ECO:0000250}.
Subcellular Localization Nucleus, nucleolus {ECO:0000250}. Cytoplasm {ECO:0000250}. Nucleus matrix {ECO:0000250}. Nucleus speckle {ECO:0000250}. Note=In punctate subnuclear structures localized adjacent to nuclear splicing speckles, called paraspeckles. Colocalizes with NONO and SFPQ in paraspeckles and perinucleolar caps in an RNA-dependent manner. May cycle between paraspeckles and nucleolus. In telophase, when daughter nuclei form, localizes to perinucleolar caps (By similarity). {ECO:0000250}.
