Application Notes
This A2BP1 Antibody (D8H8) is useful for Immunocytochemistry/Immunofluorescence, Western Blot, Immunoprecipitation and Immunohistochemistry on paraffin embedded sections. In Western Blot, a band is seen 50-55 kDa representing A2BP1. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.In Simple Western only 10-15 uL of the recommended dilution is used per data point.

Reactivity Notes

Human and mouse.

Alternate Names for A2BP1 Antibody (D8H8)

  • 2BP1

  • Fox-1 homolog A

A2BP1, also known as Ataxin-2-binding protein 1, Fox-1 homolog A and Rbfox1, is a member of the Fox-1 family, which is made up of RNA-binding proteins. A2BP1 regulates tissue-specific alternative splicing during erythropoiesis by locating the UGCAUG sequence and binding to the 5'-splice site while also preventing U2AF2 from binding to the 3' splicing site. A2BP1 may play a role in restricting the pathology of spinocerebellar ataxia type 2 (SCA2). The SCA2 gene produces ataxin-2 proteins which is a cause of familial neurodegenerative diseases. A2BP1 is primarily found in the nucleus but also seen in the cytoplasm and is expressed in the brain, heart, neurons, skeletal muscle, and embryo.
