Anti-SF3B1 polyclonal antibody

Rabbit Anti-Human SF3B1 polyclonal antibody for WB, IP. Splicing factor 3B subunit 1 (UniProt O75533; also known as Pre-mRNA-splicing factor SF3b 155 kDa subunit, SAP 155, SF3b155, Spliceosome-associated protein 155) is encoded by the SF3B1 (also known as PRP10, PRPF10, SAP155) gene (Gene ID 23451) in human. SF3a and SF3b are multiprotein complexes required for the assembly of spliceosomal A complex. SF3a consists of three subunits (SF3a60/SAP 61, SF3a66/SAP 62, SF3a120/SAP 114) and SF3b consists of at least four subunits (SF3b50/SAP 49, SF3b130/SAP 130, SF3b145/SAP 145, and SF3b155/SAP 155). SF3a/b subunits cross-link to a 25-nucleotide region in the pre-mRNA located immediately upstream to the branchpoint sequence (BPS) and help anchor U2 snRNP to the BPS. SAP 155 is a critical component of the spliceosome active site. SAP 155 cross-links to pre-mRNA on both sides of the branch site and is thus strategically positioned over the branch-site adenosine before the nucleophilic attack on the 5? splice site (ss) by the branch-site adenosine. SAP 155 is phosphorylated during splicing catalysis. SAP 155 phosphorylation is detected only in functional spliceosomes and phosphorylated SAP 155 contacts both sides of the branch site during catalysis.
