Rabbit anti-Human SF3B6 Polyclonal Antibody

Uniprot Id

Q9Y3B4

Target Species

Human

Target Name

SF3B6

Target Full Name

Splicing factor 3B subunit 6

Target Function

Involved in pre-mRNA splicing as a component of the splicing factor SF3B complex. SF3B complex is required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Directly contacts the pre-mRNA branch site adenosine for the first catalytic step of splicing. Enters the spliceosome and associates with the pre-mRNA branch site as part of the 17S U2 or, in the case of the minor spliceosome, as part of the 18S U11/U12 snRNP complex, and thus may facilitate the interaction of these snRNP with the branch sites of U2 and U12 respectively.

Target Synonyms

Ht006; P14; PM14_HUMAN; Pre mRNA branch site protein p14; Pre-mRNA branch site protein p14; SAP14; SF3B 14 kDa subunit; SF3B14; SF3B14a; Splicing factor 3B, 14 kDa subunit

Target Background

This gene encodes a 14 kDa protein subunit of the splicing factor 3b complex. Splicing factor 3b associates with both the U2 and U11/U12 small nuclear ribonucleoprotein complexes (U2 snRNP) of spliceosomes. This 14 kDa protein interacts directly with subunit 1 of the splicing factor 3b complex. This 14 kDa protein also interacts directly with the adenosine that carries out the first transesterification step of splicing at the pre-mRNA branch site.
