CRYPTOCHROME-INTERACTING BASIC HELIX-LOOP-HELIX 1
Protein DomainCRYPTOCHROME-INTERACTING BASIC HELIX-LOOP-HELIX 1 (CIB1) is an Arabidopsis thaliana basic helix-loop-helix transcription factor that binds DNA and regulates transcriptional programs linked to cell elongation. It also physically interacts with the blue-light receptor CRYPTOCHROME 2 (CRY2) and has been described as promoting flowering.
