CC -!- FUNCTION: Involved in pre-mRNA splicing as component of the
CC spliceosome. Is required in the specific splicing of CDKN1A pre-mRNA;
CC the function probably involves the recruitment of U2AF2 to the mRNA. Is
CC proposed to recruit PPIL1 to the spliceosome. May be involved in
CC cyclin-D1/CCND1 mRNA stability through the SNARP complex which
CC associates with both the 3'end of the CCND1 gene and its mRNA. Involved
CC in transcriptional regulation. Modulates TGF-beta-mediated
CC transcription via association with SMAD proteins, MYOD1-mediated
CC transcription via association with PABPN1, RB1-mediated transcriptional
CC repression, and retinoid-X receptor (RXR)- and vitamin D receptor
CC (VDR)-dependent gene transcription in a cell line-specific manner
CC probably involving coactivators NCOA1 and GRIP1. Is involved in NOTCH1-
CC mediated transcriptional activation. Binds to multimerized forms of
CC Notch intracellular domain (NICD) and is proposed to recruit
CC transcriptional coactivators such as MAML1 to form an intermediate
CC preactivation complex which associates with DNA-bound CBF-1/RBPJ to
CC form a transcriptional activation complex by releasing SNW1 and
CC redundant NOTCH1 NICD. {ECO:0000250|UniProtKB:Q13573}.
CC -!- SUBUNIT: Identified in the spliceosome C complex. Associates with
CC U4/U6-U5 tri-small nuclear ribonucleoproteins (U4/U6-U5 tri-snRNPs).
CC Interacts SKI, SMAD2,SMAD3, RBPJ, RB1, PABPN1, MAGEA1, SIRT1, FOXN3,
CC U2AF2, PPIL1, DAXX and ATP1B4. Interacts with VDR and RXRA;
CC preferentially associates with VDR:RXRA heterodimers. Interacts with
CC NCOR2. Interacts with MAML1. Interacts with NOTCH1 NICD; the
CC interaction involves multimerized NOTCH1 NICD. Forms a complex with
CC NOTCH1 NICD and MAML1; the association is dissociated by RBPJ.
CC Associates with positive transcription elongation factor b (P-TEFb).
CC Component of the SNARP complex which consists at least of SNIP1, SNW1,
CC THRAP3, BCLAF1 and PNN. {ECO:0000250|UniProtKB:Q13573,
CC ECO:0000250|UniProtKB:Q9CSN1}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q13573}.
CC -!- SIMILARITY: Belongs to the SNW family. {ECO:0000305}.
