Abstract
Endocytosis is involved in information-processing in many cell types. Recent research efforts revealed its regulatory mechanism at the synaptic terminus and regulated internalization of many G-protein coupled receptors and cell adhesion molecules. Moreover, an important break-through has been brought about by establishment of the usage of actin-dependent mechanisms. The drasitic advance in understanding of the molecular mechanism is now widening its biological significance as the global linkage among membrane traffic, cytoskeletal dynamics and signal transduction.
