This gene encodes a C2H2-type zinc finger protein and is closely related to BCL11A, a gene whose translocation may be associated with B-cell malignancies. Although the specific function of this gene has not been determined, the encoded protein is known to be a transcriptional repressor, and is regulated by the NURD nucleosome remodeling and histone deacetylase complex. Four alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.,ATL1, RIT1, CTIP2, IMD49, CTIP-2, IDDFSTA, ZNF856B, ATL1-beta, ATL1-alpha, ATL1-delta, ATL1-gamma, hRIT1-alpha,CTIP2/BCL11B
