Fig. 2. Adaptor-binding sites along the β3-integrin tail. The mapped positions of adaptors that have been shown to bind to the β3-integrin cytoplasmic tail are indicated by solid lines. Positions of adaptors that have binding sites on other integrins and are discussed in the text, but that have not been shown to bind to β3 integrin, are indicated by broken lines. Residues that are normally buried in the membrane are colored green. Residues that can be phosphorylated by various kinases (see text) are highlighted in red.
