Background Information
SF3B1, also named as SAP155, is a 1304 amino acid protein, which belongs to the SF3B1 family. SF3B1 is a subunit of the splicing factor SF3B required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. SF3B1 may also be involved in the assembly of the 'E' complex. SF3B1 belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class of nuclear pre-mRNA intron.
