Crucial roles of Rab22a in endosomal cargo recycling.
Endosomal cargo recycling lies at the heart of subcellular trafficking processes under the management of several Ras-related GTP-binding proteins (Rabs) which are coordinated by their upstream regulators and require their downstream effectors to display their functions. In this regard, several Rabs have been well-reviewed except Rab22a. Rab22a is a crucial regulator of vesicle trafficking, early endosome and recycling endosome formation. Notably, recent studies demonstrated the immunological roles of Rab22a, which are closely associated with cancers, infection and autoimmune disorders. This review provides an overview of the regulators and effectors of Rab22a. Also, we highlight the current knowledge of the role of Rab22a in endosomal cargo recycling, including the biogenesis of recycling tubules with the help of a complex with Rab22a at its core, and how different internalized cargo chooses different recycling routes thanks to the cooperation of Rab22a, its effectors and its regulators. Of note, contradictions and speculation related to endosomal cargo recycling that Rab22a brings impacts on are also discussed. Finally, this review endeavors to briefly introduce the various events impacted by Rab22a, particularly focusing on the commandeered Rab22a-associated endosomal maturation and endosomal cargo recycling, in addition to the extensively investigated oncogenic role of Rab22a.
期刊介绍:
Traffic encourages and facilitates the publication of papers in any field relating to intracellular transport in health and disease. Traffic papers span disciplines such as developmental biology, neuroscience, innate and adaptive immunity, epithelial cell biology, intracellular pathogens and host-pathogen interactions, among others using any eukaryotic model system. Areas of particular interest include protein, nucleic acid and lipid traffic, molecular motors, intracellular pathogens, intracellular proteolysis, nuclear import and export, cytokinesis and the cell cycle, the interface between signaling and trafficking or localization, protein translocation, the cell biology of adaptive an innate immunity, organelle biogenesis, metabolism, cell polarity and organization, and organelle movement.
All aspects of the structural, molecular biology, biochemistry, genetics, morphology, intracellular signaling and relationship to hereditary or infectious diseases will be covered. Manuscripts must provide a clear conceptual or mechanistic advance. The editors will reject papers that require major changes, including addition of significant experimental data or other significant revision.
Traffic will consider manuscripts of any length, but encourages authors to limit their papers to 16 typeset pages or less.
