该基因编码的蛋白质是一个螺旋环螺旋（hlh）蛋白，可以与其他hlh蛋白形成异二聚体。然而，编码的蛋白质缺乏一个基本的dna结合域，因此抑制了与其相互作用的任何hlh蛋白的dna结合。[由RefSeq提供，2011年8月]
The protein encoded by this gene is a helix-loop-helix (HLH) protein that can form heterodimers with other HLH proteins. However, the encoded protein lacks a basic DNA-binding domain and therefore inhibits the DNA binding of any HLH protein with which it interacts. [provided by RefSeq, Aug 2011]
