Anti-SF3B1 antibody produced in rabbit

产品说明

一般描述

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).

特异性

Anti-SF3B1 (AB3) polyclonal antibody reacts with human, mouse, rat, chicken, canine, and zebrafish splicing factor 3b, subunit 1, 155 kDa proteins.

免疫原

Synthetic peptide directed towards the N terminal region of human SF3B1

应用

Anti-SF3B1 (AB3) 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.

生化/生理作用

SF3B1 is 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. The carboxy-terminal two-thirds of subunit 1 have 22 non-identical, tandem HEAT repeats that form rod-like, helical structures.This gene encodes subunit 1 of the splicing factor 3b protein complex.

The carboxy-terminal two-thirds of subunit 1 have 22 non-identical, tandem HEAT repeats that form rod-like, helical structures. Alternative splicing results in multiple transcript variants encoding different isoforms.
