Immunoglobulin superfamily: structure, function and relationship to other receptor molecules.
The immunoglobulin superfamily includes the most diverse group of receptors known. They are united by the possession of a common structural feature, the immunoglobulin homology domain. They are found in species from insects to man. They are central to both the humoral and cell mediated immune reactions; they serve as cell surface receptors responsible for positional ques during embryonic development, as well as viral and growth factor receptors. They function in conjunction with other receptor families including the integrins and selectins. Thus, they are frequently parts of adhesive cascades and as such activate signal transducing systems required for the expression or activation of other cell surface receptors. They continue to be the targets of intense investigation into the molecular basis of adhesive interactions.
