CC -!- FUNCTION: RNA-binding protein that plays several role in the regulation
CC of pre- and post-transcriptional processes. Implicated in tissue-
CC specific regulation of gene transcription and alternative splicing of
CC several pre-mRNAs. Binds to and stimulates transcription from the tumor
CC suppressor TXNIP gene promoter; may thus be involved in tumor
CC suppression. When associated with SAFB, binds to and stimulates
CC transcription from the SREBF1 promoter. Associates with nascent mRNAs
CC transcribed by RNA polymerase II. Component of the supraspliceosome
CC complex that regulates pre-mRNA alternative splice site selection. Can
CC either activate or suppress exon inclusion; acts additively with TRA2B
CC to promote exon 7 inclusion of the survival motor neuron SMN2.
CC Represses the splicing of MAPT/Tau exon 10. Binds preferentially to
CC single-stranded 5'-CC[A/C]-rich RNA sequence motifs localized in a
CC single-stranded conformation; probably binds RNA as a homodimer. Binds
CC non-specifically to pre-mRNAs. Also plays a role in the cytoplasmic
CC TNFR1 trafficking pathways; promotes both the IL-1-beta-mediated
CC inducible proteolytic cleavage of TNFR1 ectodomains and the release of
CC TNFR1 exosome-like vesicles to the extracellular compartment (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homomultimer. Found in the supraspliceosome complex.
CC Identified in the spliceosome C complex. Forms a complex with ILF2,
CC ILF3, YLPM1, KHDRBS1, NCOA5 and PPP1CA. Interacts with CLK2, KHDRBS2,
CC KHDRBS3, SAFB/SAFB1, TRA2B and YTHDC1. Interacts with ERAP1; the
CC interaction is RNA-independent (By similarity). Interacts with
CC PPIA/CYPA (By similarity). {ECO:0000250|UniProtKB:P38159,
CC ECO:0000250|UniProtKB:Q9WV02}.
CC -!- SUBCELLULAR LOCATION: Nucleus. Note=Localizes in numerous small
CC granules in the nucleus. Component of ribonucleosomes (By similarity).
CC {ECO:0000250}.
CC -!- DOMAIN: The RRM domain is necessary for RNA-binding, but not for splice
CC site selection, indicating that its splicing activity does not require
CC direct binding to RNA. {ECO:0000250}.
CC -!- PTM: O-glycosylated. {ECO:0000250}.
CC -!- PTM: Arg-185 is dimethylated, probably to asymmetric dimethylarginine.
CC {ECO:0000250}.
