A binding protein is any protein that acts as an agent to bind two or more molecules together. Examples include: DNA-binding protein Single-strand binding protein Telomere-binding protein RNA-binding protein Poly(A)-binding protein Nuclear cap-binding protein complex CREB-binding protein Calcium-binding protein Calcium-binding protein 1 S100 calcium-binding protein A1 TATA-binding protein Actin-binding protein Most actin binding proteins bind on the actin surface, despite having different functions and structures.
