Summary
SART1 (spliceosome associated factor 1, recruiter of U4/U6.U5 tri-snRNP, HGNC:10538) is a protein-coding gene on chromosome 11q13.1, encoding U4/U6.U5 tri-snRNP-associated protein 1 (O43290). Plays a role in mRNA splicing as a component of the U4/U6-U5 tri-snRNP, one of the building blocks of the spliceosome. It is a common-essential gene (DepMap: required in 98.7% of cancer cell lines).
This gene encodes two proteins, the SART1(800) protein expressed in the nucleus of the majority of proliferating cells, and the SART1(259) protein expressed in the cytosol of epithelial cancers. The SART1(259) protein is translated by the mechanism of -1 frameshifting during posttranscriptional regulation; its full-length sequence is not published yet. The two encoded proteins are thought to be involved in the regulation of proliferation. Both proteins have tumor-rejection antigens. The SART1(259) protein possesses tumor epitopes capable of inducing HLA-A2402-restricted cytotoxic T lymphocytes in cancer patients. This SART1(259) antigen may be useful in specific immunotherapy for cancer patients and may serve as a paradigmatic tool for the diagnosis and treatment of patients with atopy. The SART1(259) protein is found to be essential for the recruitment of the tri-snRNP to the pre-spliceosome in the spliceosome assembly pathway.

- p110, a novel human U6 snRNP protein and U4/U6 snRNP recycling factor (PMID:12032085)
- hypothesize that polymorphic variation within the SART-1 gene may account for individuals developing atopy (PMID:12189166)
- hypoxia-associated factor (HAF), also known as SART1, a protein expressed in proliferating cells, binds and ubiquitinates HIF-1alpha in vitro, and both binding and E3 ligase activity are mediated by HAF amino acids 654 to 800 (PMID:18838541)
- This study identifies SART1 as a previously unidentified regulator of c-FLIP and drug-induced activation of caspase-8. (PMID:22027693)
- SART1 exerts its anti-Hepatitis C virus action through direct transcriptional regulation for some Interferon stimulating genes and alternative splicing for others. (PMID:25481564)
- Data indicate that mutant VHL can protect HIF1alpha from SART1-dependent degradation in normoxic conditions, but this protection is lost in hypoxic settings, favoring hypoxia-dependent ccRCC proliferation. (PMID:25915846)
- SART1 has a role in IFN-mediated anti-Hepatitis B virus response (PMID:28077916)
- Patients with clear cell renal carcinoma with high HAF transcript or protein levels showed significantly decreased overall survival compared with those with low HAF. Functional study shows that HAF promotes neurofibromin ubiquitination and degradation independently of oxygen and pVHL, resulting in Ras-ERK pathway activation. (PMID:30705246)

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 194 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.
