Summary
SNRNP40 (small nuclear ribonucleoprotein U5 subunit 40, HGNC:30857) is a protein-coding gene on chromosome 1p35.2, encoding U5 small nuclear ribonucleoprotein 40 kDa protein (Q96DI7). Required for pre-mRNA splicing as component of the activated spliceosome. It is a selective cancer dependency (DepMap: 90.0% of cell lines).
This gene encodes a component of the U5 small nuclear ribonucleoprotein (snRNP) particle. The U5 snRNP is part of the spliceosome, a multiprotein complex that catalyzes the removal of introns from pre-messenger RNAs.

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.
