E BOX MOTIFS Meaning and
Definition
-
E box motifs refer to a specific DNA sequence motif that is commonly found in the promoter regions of genes. These motifs are involved in the regulation of gene expression and have been identified in a wide range of organisms, including humans, insects, and plants. E box motifs are recognized and bound by basic helix-loop-helix (bHLH) transcription factors, which are a class of transcription factors that play important roles in development and cellular differentiation.
The typical consensus sequence of an E box motif is 5'-CANNTG-3', where N can represent any nucleotide. This sequence is recognized by bHLH transcription factors, which form homo- or heterodimers to bind to the E box motif and initiate gene transcription. The binding of bHLH factors to E box motifs can either activate or repress gene expression, depending on the specific context and the interacting partners.
E box motifs are found in the regulatory regions of genes involved in various biological processes, such as cell cycle control, metabolism, tissue-specific gene expression, and response to environmental stimuli. They have been particularly well-studied in the context of circadian rhythm regulation, as they are known to be critical for the rhythmic expression of clock genes.
In summary, E box motifs are short DNA sequence motifs that serve as binding sites for bHLH transcription factors, playing a crucial role in the regulation of gene expression and diverse biological processes.
