Cbl proteins control multiple cellular processes by acting as ubiquitin ligases and multifunctional adaptor molecules. They are involved in the control of cell proliferation, differentiation and cell morphology, as well as in pathologies such as autoimmune diseases, inflammation and cancer. Here we review recent advances in understanding the role of Cbl and the importance of a growing repertoire of Cbl-interacting proteins in the regulation of signaling pathways triggered by growth factors, antigens, cell adhesion, cytokines and hormones. We also address key issues of the nature of proteins that bind Cbl in particular cells, where they are located, and how they are altered or traffic within cells upon stimulation. It is becoming obvious that temporal and spatial changes in Cbl signaling networks are essential for the control of physiological processes in a variety of cells and organs and that their deregulation can result in the development of human diseases.
