CC -!- FUNCTION: Component of the SIN3-repressing complex. Enhances the CC ability of SIN3-HDAC1-mediated transcriptional repression. When CC tethered to the promoter, it can direct the formation of a CC repressive complex to core histone proteins. Auxiliary component CC of the splicing-dependent multiprotein exon junction complex (EJC) CC deposited at splice junction on mRNAs. The EJC is a dynamic CC structure consisting of core proteins and several peripheral CC nuclear and cytoplasmic associated factors that join the complex CC only transiently either during EJC assembly or during subsequent CC mRNA metabolism. Component of the ASAP and PSAP complexes which CC bind RNA in a sequence-independent manner and are proposed to be CC recruited to the EJC prior to or during the splicing process and CC to regulate specific excision of introns in specific transcription CC subsets. The ASAP complex can inhibit mRNA processing during in CC vitro splicing reactions. The ASAP complex promotes apoptosis and CC is disassembled after induction of apoptosis. Involved in the CC splicing modulation of BCL2L1/Bcl-X (and probably other apoptotic CC genes); specifically inhibits the formation of proapoptotic CC isoforms such as Bcl-X(S); the activity is different from the CC established EJC assembly and function. CC -!- SUBUNIT: Found in a mRNA splicing-dependent exon junction complex CC (EJC). Component of the heterotrimeric ASAP (apoptosis- and CC splicing-associated protein) and PSAP complexes consisting of CC RNPS1, SAP18 and either ACIN1 or PNN, respectively; the ASAP and CC PSAP complexes probably are formed mutually exclusive. For the CC ASAP complex, the association of SAP18 seems to require a CC preformed RNPS1:ACIN1 complex. Forms a complex with SIN3A and CC HDAC1. Interacts with SUFU. CC -!- INTERACTION: CC Q13547:HDAC1; NbExp=2; IntAct=EBI-1044156, EBI-301834; CC -!- SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Nucleus speckle. CC Note=Shuttles between the nucleus and the cytoplasm. Colocalizes CC with ACIN1 and SRSF2 in nuclear speckles. CC -!- TISSUE SPECIFICITY: Ubiquitous. CC -!- SIMILARITY: Belongs to the SAP18 family.
