TATA-Binding Protein

Definition

The TATA-binding protein (TBP) is a universal adapter molecule that binds specifically to the TATA box and assists in positioning RNA polymerase at the correct starting point for transcription.

Analogy

If we continue with our helicopter analogy, think about TBP as air traffic control. It communicates with our helicopter (RNA Polymerase), guiding it safely onto our landing pad (TATA Box).
