About SF1

Cytogenetic location: 11q13.1 Genomic coordinates (GRCh38): 11:64,764,606-64,778,542 (from NCBI)

This gene has 21 transcripts (splice variants), 183 orthologues and 4 paralogues. Ubiquitous expression in bone marrow (RPKM 62.1), testis (RPKM 36.4) and 25 other tissues.

Summary

This gene encodes a nuclear pre-mRNA splicing factor. The encoded protein specifically recognizes the intron branch point sequence at the 3' splice site, together with the large subunit of U2 auxiliary factor (U2AF), and is required for the early stages of spliceosome assembly. It also plays a role in nuclear pre-mRNA retention and transcriptional repression. The encoded protein contains an N-terminal U2AF ligand motif, a central hnRNP K homology motif and quaking 2 region which bind a key branch-site adenosine within the branch point sequence, a zinc knuckles domain, and a C-terminal proline-rich domain. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2016]
