B lymphocytes perceive antigen in their environment by virtue of membraneassociated immunoglobulin molecules (mlg). Membrane immunoglobulins have extensive structural homology to immunoglobulins which are secreted by differentiated daughter cells. They differ in that mlg possess a C-terminal spacer and attached transmembrane and cytoplasmic domains (the latter is only 3 amino acids for mIgM and mIgD). In spite of their limited cytoplasmic structure, mlg crosslinking initiates cytoskeletal anchorage, receptor endocytosis, antigen processing and presentation, and cell proliferation and differentiation. Until recently, it was unclear how the short cytoplasmic tail of mlg could interact with the multiple cytoplasmic effectors necessary for these functions. However, studies conducted over the past three years have enormously advanced our understanding of this process. It is clear that, in its resting state, the antigen receptor is an extended complex composed of the antigen recognition substructure, mlg, a noncovalently-associated transducer substructure, lg-a/-/?/->; and various cytoplasmic effector enzymes, e.g. the src-family tyrosine kinase Lyn. Finally, some
