Anti-SF3B1 (AB1) antibody produced in rabbit

General description

Splicing factor 3b, subunit 1, 155 kDa (SF3B1, SAP155, PRP10) is a subunit of the splicing factor 3b protein complex, which along with splicing factor 3a and 12S RNA forms the U2 small nuclear ribonucleoproteins complex (U2 snRNP). SF3B1 is also a component of the minor U12-type spliceosome. Mutations of SF3B1have been linked to myelodysplastic syndromes (MDS) and chronic lymphocytic leukemia (CLL).

Specificity

Anti-SF3B1 (AB1) polyclonal antibody reacts with zebrafish, chicken, canine, human, mouse, and rat splicing factor 3b, subunit 1, 155 kDa proteins.

Immunogen

Synthetic peptide directed towards the middle region of human SF3B1

Application

Anti-SF3B1 (AB1) polyclonal antibody is used to tag splicing factor 3b, subunit 1, 155 kDa for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to determine the roles of splicing factor 3b, subunit 1, 155 kDa in U2-snRNP and U12-type spliceosome formation and function.

Biochem/physiol Actions

SF3B1 is the subunit 1 of the splicing factor 3b protein complex. Splicing factor 3b, together with splicing factor 3a and a 12S RNA unit, forms the U2 small nuclear ribonucleoproteins complex (U2 snRNP). The splicing factor 3b/3a complex binds pre-mRNA upstream of the intron′s branch site in a sequence independent manner and may anchor the U2 snRNP to the pre-mRNA. Splicing factor 3b is also a component of the minor U12-type spliceosome.

Sequence

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.
