WebThe μE motifs of the immunoglobulin μ heavy-chain gene enhancer bind ubiquitously expressed proteins of the basic helix-loop-helix (bHLH) family. These elements work together with other, more tissue-restricted elements to produce B-cell-specific enhancer activity by presently undefined combinatorial mechanisms. WebThe basic helix-loop-helix gene epicardin/capsulin/Pod1 (official gene symbol: Tcf21) is specifically expressed in the chick and mouse proepicardium, epicardium and in the pericardium ( Robb et al., 1998 ). It is believed to act as a repressor of cell differentiation ( Funato et al., 2003 ).

Web13 aug. 2024 · Basic helix–loop–helix (bHLH) proteins, one of the most important and largest transcription factor family in plants, play important roles in regulating growth and … WebThese motifs include helix-turn-helix (HTH), helix-loop-helix (HLH), zinc fingers, and leucine zippers. HTH and HLH are similar in that they both contain two α-helices separated by a turn (short) and a loop (long) region. Both of these usually bind as dimers to inverted repeats in the DNA sequence. WebThe zipper family comprises many members, some of which can cross-dimerize and recognize asymmetrical sequences. Another family of factors comprises the helix-loop-helix proteins, which have the same type of basic region but differ in that they have two helical dimerization domains separated by a loop region. ttu tax services
