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.
