Summary
RNPS1 (RNA binding protein with serine rich domain 1, HGNC:10080) is a protein-coding gene on chromosome 16p13.3, encoding RNA-binding protein with serine-rich domain 1 (Q15287). Part of pre- and post-splicing multiprotein mRNP complexes. It is a common-essential gene (DepMap: required in 98.0% of cancer cell lines).
This gene encodes a protein that is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. mRNA surveillance detects exported mRNAs with truncated open reading frames and initiates nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. This protein binds to the mRNA and remains bound after nuclear export, acting as a nucleocytoplasmic shuttling protein. This protein contains many serine residues. Several transcript variants encoding different isoforms have been found for this gene.

Function. Part of pre- and post-splicing multiprotein mRNP complexes. Auxiliary component of the splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junction on mRNAs. The EJC is a dynamic structure consisting of core proteins and several peripheral nuclear and cytoplasmic associated factors that join the complex only transiently either during EJC assembly or during subsequent mRNA metabolism. Component of the ASAP and PSAP complexes which bind RNA in a sequence-independent manner and are proposed to be recruited to the EJC prior to or during the splicing process and to regulate specific excision of introns in specific transcription subsets. The ASAP complex can inhibit RNA processing during in vitro splicing reactions. The ASAP complex promotes apoptosis and is disassembled after induction of apoptosis. Enhances the formation of the ATP-dependent A complex of the spliceosome. Involved in both constitutive splicing and, in association with SRP54 and TRA2B/SFRS10, in distinctive modulation of alternative splicing in a substrate-dependent manner. Involved in the splicing modulation of BCL2L1/Bcl-X (and probably other apoptotic genes); specifically inhibits formation of proapoptotic isoforms such as Bcl-X(S); the activity is different from the established EJC assembly and function. Participates in mRNA 3’-end cleavage. Involved in UPF2-dependent nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. Also mediates increase of mRNA abundance and translational efficiency. Binds spliced mRNA 20-25 nt upstream of exon-exon junctions.
Subunit / interactions. Found in mRNA splicing-dependent exon junction complexes (EJC). Found in a post-splicing complex with NXF1, RBM8A, UPF1, UPF2, UPF3A, UPF3B and RNPS1. Component of the heterotrimeric ASAP (apoptosis- and splicing-associated protein) and PSAP complexes consisting of RNPS1, SAP18 and either ACIN1 or PNN, respectively; the ASAP and PSAP complexes probably are formed mutually exclusive. Component of the active spliceosome. Associates with polysomes. Interacts with the cleaved p110 isoform of CDC2L1, CSNK2A1, PNN, SART3, SRP54, SRRM1 and TRA2B/SFRS10.
Subcellular location. Nucleus. Nucleus speckle. Cytoplasm.
Tissue specificity. Ubiquitous.
Post-translational modifications. Phosphorylated on one or more of the four Ser/Thr residues (Ser-43, Thr-49, Ser-52 or Ser-53). Ser-53 phosphorylation site is important for splicing and translation stimulation activity in vitro.
Domain organisation. The RRM domain is required for the formation of the ASAP complex.
Similarity. Belongs to the splicing factor SR family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 164 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
