該基因編碼一種參與普遍存在的轉錄因子nf-kappab激活的蛋白質。該蛋白和組蛋白去乙酰化酶HDAC3和Notch共加壓因子復合物相關，從而充當Notch靶基因的轉錄抑制因子它也是αβT細胞發育所必需的在x染色體上發現了一個相關的假基因，而在6號染色體上發現了一個相關的無內含子的逆轉錄酶，該逆轉錄酶具有完整的cds并且可能具有功能。[由RefSeq提供，2010年5月]
This gene encodes a protein that is involved in the activation of the ubiquitous transcription factor NF-kappaB. This protein is associated with the the histone deacetylase HDAC3 and with the Notch corepressor complex, and it thereby acts as a transcriptional repressor of Notch target genes. It is also required for alphabeta T cell development. A related pseudogene has been identified on chromosome X, while a related and intronless retrocopy, which has an intact CDS and may be functional, is located on chromosome 6.
