Target Information
Splicing factor 1 (SF1) is a nuclear pre-mRNA splicing factor that specifically recognizes the intron branch point sequence at the 3′ splice site together with the large subunit of U2 auxiliary factor (U2AF). It is essential for the early stages of spliceosome assembly and also plays roles in nuclear pre-mRNA retention and transcriptional repression.
The protein contains:
- N-terminal U2AF ligand motif
- Central hnRNP K homology motif and quaking 2 region (binds branch-site adenosine)
- Zinc knuckles domain
- C-terminal proline-rich domain
Alternative splicing results in multiple transcript variants.
