Function

The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. Required for the integrity and for normal function of the Golgi apparatus and the trans-Golgi network. Plays a role in insulin-stimulated translocation of GLUT4 to the cell membrane. Plays a role in M6PR transport from the trans-Golgi network to endosomes. Plays a role in the internalization of EGFR from the cell membrane into endosomes. Plays a role in the maturation of phagosomes that engulf pathogens, such as S.aureus and M.tuberculosis.

Activity summary

RAB31 also known as RAB22B belongs to the RAB family which plays an important role in vesicular trafficking. It is a small GTPase with a mass of approximately 23 kDa. RAB31 is mainly expressed in epithelial tissues and certain cancer cell lines. It regulates vesicle formation movement and fusion by cycling between an active GTP-bound state and an inactive GDP-bound state. This cycling is important for its function in the intracellular transport system.

Biological function summary

RAB31 influences early endosome dynamics and directly impacts the sorting and recycling of receptors. It associates with effector proteins to form protein complexes that facilitate endocytosis and exocytosis processes. It also interacts with other Rab proteins to ensure proper membrane specificity and temporal regulation within cellular compartments. This behavior highlights its role in maintaining cellular homeostasis and responsiveness to environmental changes.

Pathways

Studies have shown that RAB31 contributes significantly to the endocytic pathway and the insulin signaling pathway. It has functional interactions with proteins like RAB5 and RAB11 both of which are key regulators of endosomal trafficking. RAB31 ensures a proper transport cycle that influences receptor recycling and signaling impacting how cells respond to growth factors and hormones.

Associated diseases and disorders

Research implicates RAB31 in the progression of certain cancers such as breast cancer due to its established role in vesicle trafficking and receptor recycling which can affect cell growth and division. Its altered expression levels may intersect with proteins such as EGFR leading to abnormal signaling cascades. Furthermore RAB31 has associations with metabolic disorders as disruptions in insulin signaling pathways may contribute to diabetes showcasing its diverse influence on human health.
