该基因编码一种参与普遍存在的转录因子nf-kappab激活的蛋白质。该蛋白和组蛋白去乙酰化酶HDAC3和Notch共加压因子复合物相关，从而充当Notch靶基因的转录抑制因子它也是αβT细胞发育所必需的在x染色体上发现了一个相关的假基因，而在6号染色体上发现了一个相关的无内含子的逆转录酶，该逆转录酶具有完整的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.
