H12.rar

: When no ligand is present, H12 is often disordered, allowing corepressors like N-CoR to bind and repress gene activity.

: When an agonist (ligand) binds, H12 folds and "caps" the ligand-binding pocket. This creates a surface for coactivators to bind, triggering gene expression. H12.rar

: The transition of H12 from a disordered state to a structured helix is essential for the precise regulation of RAR activity . Alternative Context: Construction : When no ligand is present, H12 is

In a completely different context, can also refer to a specific type of corrugated metal sheet (profnastil) with a 12mm crease height used for roofing and facades, sometimes associated with the brand RAR Acoperis . : The transition of H12 from a disordered

"H12.rar" refers to the interaction between the region and the Retinoic Acid Receptor (RAR) , a critical mechanism in molecular biology for controlling gene transcription. Key Scientific Concepts

: This is the C-terminal activation helix of the receptor. Its position acts as a "molecular switch". Transcriptional Regulation :
