该基因编码的蛋白质属于DNA结合抑制剂家族，其成员是包含螺旋环螺旋（HLH）结构域而非基本结构域的转录调控因子DNA结合抑制剂家族成员通过HLH结构域抑制碱式螺旋环螺旋转录因子的异二聚体，以显性负性方式抑制其功能这种蛋白可能在负调节细胞分化中起作用。这个基因的一个假基因位于3号染色体上。[由RefSeq提供，2011年8月]
The protein encoded by this gene belongs to the inhibitor of DNA binding family, members of which are transcriptional regulators that contain a helix-loop-helix (HLH) domain but not a basic domain. Members of the inhibitor of DNA binding family inhibit the functions of basic helix-loop-helix transcription factors in a dominant-negative manner by suppressing their heterodimerization partners through the HLH domains. This protein may play a role in negatively regulating cell differentiation. A pseudogene of this gene is located on chromosome 3. [provided by RefSeq, Aug 2011]
