Summary
SNIP1 (Smad nuclear interacting protein 1, HGNC:30587) is a protein-coding gene on chromosome 1p34.3, encoding Smad nuclear-interacting protein 1 (Q8TAD8). Required for pre-mRNA splicing as component of the spliceosome. It is a selective cancer dependency (DepMap: 81.3% of cell lines).
This gene encodes a protein that contains a coiled-coil motif and C-terminal forkhead-associated (FHA) domain. The encoded protein functions as a transcriptional coactivator that increases c-Myc activity and inhibits transforming growth factor beta (TGF-beta) and nuclear factor kappa-B (NF-kB) signaling. The encoded protein also regulates the stability of cyclin D1 mRNA, and may play a role in cell proliferation and cancer progression. Mutations in this gene are a cause of psychomotor retardation, epilepsy, and craniofacial dysmorphism (PMRED).

Function. Required for pre-mRNA splicing as component of the spliceosome. As a component of the minor spliceosome, involved in the splicing of U12-type introns in pre-mRNAs. Down-regulates NF-kappa-B signaling by competing with RELA for CREBBP/EP300 binding. Involved in the microRNA (miRNA) biogenesis. May be involved in cyclin-D1/CCND1 mRNA stability through the SNARP complex which associates with both the 3’end of the CCND1 gene and its mRNA.
Subunit / interactions. Component of activated spliceosome complexes. Component of the minor spliceosome, which splices U12-type introns. Binds SMAD4 and CREBBP/EP300. Binds the SMAD1/OAZ1/PSMB4 complex. Interacts with DROSHA and SMARCA4. Component of the SNARP complex which consists at least of SNIP1, SNW1, THRAP3, BCLAF1 and PNN.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 159 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.
