Interestingly, both FOX-1 and FOX-2, also known as A2BP1 (ataxin-2 binding protein 1) and RBM9 (RNA binding motif protein 9), have been identified as interaction partners of ataxin-1 (ATXN1), which is implicated in spinocerebellar ataxia type 1 (SCA1) [16]. This evidence concerns the gene RBFOX2 and spinocerebellar ataxia type 1.
