    This antibody was raised by a genetic immunization technique. Genetic immunization can be used to generate antibodies by directly delivering antigen-coding DNA into the animal, rather than injecting a protein or peptide (Tang et al. PubMed: 1545867; Chambers and Johnston PubMed: 12910245; Barry and Johnston PubMed: 9234514). The animal`s cells produce the protein, which stimulates the animal`s immune system to produce antibodies against that particular protein. A vector coding for a partial fusion protein was used for genetic immunisation of a mouse and the resulting serum was tested in Western blot against an E.coli lysate containing that partial fusion protein. Genetic immunization offers enormous advantages over the traditional protein-based immunization method. DNA is faster, cheaper and easier to produce and can be produced by standard techniques readily amenable to automation. Furthermore, the antibodies generated by genetic immunization are usually of superior quality with regard to specificity, affinity and recognizing the native protein.

Application Abreviews Notes
WB 1/1000. Predicted molecular weight: 145 kDa.

This antibody has been tested in Western blot against an E.coli lysate containing the partial recombinant fusion protein used as an immunogen. We have no data on detection of endogenous protein.

Target

  • FunctionSubunit 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. May also be involved in the assembly of the 'E' complex. Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class of nuclear pre-mRNA intron.
  • Sequence similaritiesBelongs to the SF3B1 family.
    Contains 11 HEAT repeats.
  • Post-translational
    modifications
    Phosphorylated. Phosphorylation occurs concomitantly with the splicing catalytic steps. Phosphorylation on Thr-244, Thr-248 and Thr-313 by cyclin-dependent kinases promotes interaction with PPP1R8 during mitosis.
  • Cellular localizationNucleus speckle. During mitosis, transiently dispersed from the nuclear speckles to the cytoplasm.

Thank you for your enquiry. Isotype controls are generally controls derived from the same species as well as being the same immunoglobulin isotype. In this case the monoclonal ab18475 derived from Armenian Hamster is not the best control for the mo...
