; 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 ....

A DNA-binding basic region is followed by two alpha-helices separated by a variable loop region; HLH forms homo- and heterodimers, dimerization creates a parallel, left-handed, four helix bundle; the basic region N-terminal to the first amphipathic helix mediates high-affinity DNA-binding; there are several groups of HLH proteins: those (E12/E47) which bind specific hexanucleotide sequences such as E-box (5-CANNTG-3) or StRE 5-ATCACCCCAC-3), those lacking the basic domain (Emc, Id) function as negative regulators since they fail to bind DNA, those (hairy, E(spl), deadpan) which repress transcription although they can bind specific hexanucleotide sequences such as N-box (5-CACGc/aG-3), those which have a COE domain (Collier/Olf-1/EBF) which is involved in both in dimerization and in DNA binding, and those which bind pentanucleotides ACGTG or GCGTG and
