Homo sapiens

Also known as PRP21; PRPF21; SAP114; SF3A120

Gene ID: 10291 | Gene type: protein coding

About SF3A1

Cytogenetic location: 22q12.2 Genomic coordinates (GRCh38): 22:30,331,988-30,356,894 (from NCBI)

This gene has 10 transcripts (splice variants) and 210 orthologues. Ubiquitous expression in testis (RPKM 34.4), ovary (RPKM 24.5) and 25 other tissues.

Summary

This gene encodes a subunit of the splicing factor 3a protein complex. The splicing factor 3a heterotrimer is a component of the mature U2 small nuclear ribonucleoprotein particle (snRNP). U2 small nuclear ribonucleoproteins play a critical role in spliceosome assembly and pre-mRNA splicing. [provided by RefSeq, Aug 2014]
