Spang A 2009 Proteins are endocytosed by various pathways into the cell. All these pathways converge at the level of the early endosome. The fate of the early endosome and how proteins are sorted into recycling and late endosomes/multi-vesicular body is a matter of debate and intense research. Obviously, the transition from early to late endosome poses an interesting logistic problem and would merit attention on an intellectual level. Numerous diseases are also caused by defects in turning off/over signaling molecules or mis-sorting of proteins at the level of the early endosome. This brief review aims to discuss different molecular mechanisms whereby early-to-late endosome transition could be achieved. https://sonar.ch/global/documents/184688 eng info:eu-repo/semantics/altIdentifier/doi/10.1515/BC.2009.056 info:eu-repo/semantics/altIdentifier/pmid/19361275 Biological chemistry. - 2009 Animals Endocytosis Endosomes Guanine Nucleotide Exchange Factors Humans rab GTP-Binding Proteins rab5 GTP-Binding Proteins On the fate of early endosomes. http://purl.org/coar/resource_type/c_6501
