Integrins are the principal receptors used by animal cells to bind to the extracellular matrix. They are heterodimers and function as transmembrane linkers between the extracellular matrix and the actin cytoskeleton. A cell can regulate the adhesive activity of its integrins from within. An example of an integrin containing cell junction is

Choose correct statements about recognition mechanism of TBP ;

A. TBP causes the minor groove to be widened to an almost flat conformation

B. It also bends the DNA by an angle of ~120o

C. The interaction between TBP and DNA involves maximum number of hydrogen bonds between the protein and the edges of the base.

D. Much of the specificity is imposed by two pairs of phenylalanine side chains that intercalate between the base pairs at either end of the recognition sequence and drive the strong bend in the DNA.
