Ataxin-1-like (Atxn1l)

Chromatin-binding factor that repress Notch signaling in the absence of Notch intracellular domain by acting as a CBF1 corepressor. Binds to the HEY promoter and may assist, together with NCOR2, RBPJ-mediated repression (By similarity).

Can suppress the cytotoxicity of ATXN1 in spinocerebellar ataxia type 1 (SCA1) (PubMed:16121196). In concert with CIC and ATXN1, involved in brain development (PubMed:28288114).
