G-box binding factors (GBFs) are transcription factors that bind to the G-box DNA motif, which is a specific sequence found in the promoter regions of many plant genes. The G-box sequence has the core consensus of CACGTG and is involved in the regulation of various biological processes such as light response, flower development, and stress tolerance. GBFs play crucial roles in these processes by interacting with other proteins to modulate gene expression through chromatin remodeling or recruitment of co-activators/repressors. Examples of GBFs include basic helix-loop-helix (bHLH) transcription factors, such as HY5 and PIFs, which have been extensively studied in the context of plant growth, development, and environmental responses.
Proteiner som binder till DNA. Till denna familj hör proteiner som binder till såväl dubbelsträngat som enkelsträngat DNA, och den omfattar även specifika DNA-bindande proteiner i serum som kan användas som markörer för tumörsjukdomar.
Core Binding Factors (CBF) refer to a group of transcription factors that play critical roles in hematopoiesis, the process of blood cell development. The CBF complex is typically composed of two key subunits: a DNA-binding component called CBFα (also known as RUNX1 or AML1) and a non-DNA-binding component called CBFβ (also known as RUNX1T1 or MTG8). These subunits form a heterodimer that binds to specific DNA sequences, regulating the expression of target genes involved in hematopoiesis.
