; InterPro: IPR011598 The helix-loop-helix (HLH) DNA-binding domain consists of a closed bundle of four helices in a left-handed twist with two crossover connections. The HLH domain directs dimerisation, and is juxtaposed to basic regions to create a DNA interaction interface surface that recognises specific DNA sequences. Basic region/HLH (bHLH) proteins regulate diverse biological pathways []. bHLH proteins include MyoD [], SREBPs (sterol regulatory element binding proteins) [], and yeast Pho4 (phosphatase system) []. In certain proteins the bHLH domain contains a leucine-zipper motif. The bHLH/leucine zipper (bHLHZip) domain specifies dimerisation within a network of proteins and determines sequence-specific DNA binding []. bHLHZip domains occur in the transcription factors Myc, Mad, Max and Usf [, ]. This entry is bHLHZip, which covers the bHLH domain and the leucine zipper motif, when present.; PDB: 1NLW_A 1NKP_D 1A93_A 2A93_A 1AM9_C 3U5V_A 1A0A_B 2QL2_C 1UKL_C 1AN4_B .... |
