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 sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. That Rab is involved in polarized vesicular trafficking and neurotransmitter release. Together with RAB11A, RAB3IP, the exocyst complex, PARD3, PRKCI, ANXA2, CDC42 and DNMBP promotes transcytosis of PODXL to the apical membrane initiation sites (AMIS), apical surface formation and lumenogenesis (PubMed:20890297). Regulates the compacted morphology of the Golgi (PubMed:26209634). Together with MYO5B and RAB11A participates in epithelial cell polarization (PubMed:21282656). Also involved in membrane trafficking to the cilium and ciliogenesis (PubMed:21844891, PubMed:30398148). Together with MICALL2, may also regulate adherens junction assembly (By similarity). May play a role in insulin-induced transport to the plasma membrane of the glucose transporter GLUT4 and therefore play a role in glucose homeostasis (By similarity). Involved in autophagy (PubMed:27103069). Participates in the export of a subset of neosynthesized proteins through a Rab8-Rab10-Rab11-dependent endososomal export route (PubMed:32344433). Targeted to and stabilized on stressed lysosomes through LRRK2 phosphorylation (PubMed:30209220). Suppresses stress-induced lysosomal enlargement through EHBP1 and EHNP1L1 effector proteins (PubMed:30209220).

Activity summary

RAB8A is a small GTPase also referred to as Ras-related protein Rab-8A involved in intracellular membrane trafficking. It plays a critical role in the regulation of exocytosis the process by which cells release substances to the extracellular space. RAB8A mainly functions by cycling between an inactive GDP-bound form and an active GTP-bound form facilitating vesicle budding transport and fusion with target membranes. This protein is expressed in various tissues including the brain and pancreas where it assists in important cellular functions. RAB8A has a molecular mass of approximately 24 kDa.

Biological function summary

The small GTPase RAB8A contributes to the biosynthetic transport from the trans-Golgi network to the plasma membrane. It performs this activity in coordination with other proteins as part of a larger complex. RAB8A also plays an essential role in cilia formation and maintenance affecting cell polarity and signaling functions. The protein's ability to regulate vesicle movement makes it important for cellular homeostasis and communication.

Pathways

The regulatory function of RAB8A is significant in the ciliary membrane trafficking pathway and the insulin signaling pathway. Within these pathways RAB8A interacts closely with other proteins like Rab11 and Rabin8 which help support its roles in directing vesicle transport. These interactions are essential for proper cellular signaling and the maintenance of polarized cellular structures further supporting the function of various cellular pathways.

Associated diseases and disorders

The dysfunction of RAB8A has associations with certain ciliopathies notably Bardet-Biedl syndrome. This condition involves abnormalities in cilia structure and function leading to symptoms like kidney disease vision impairment and obesity. Moreover disruptions in RAB8A have connections with insulin resistance implicating it in metabolic disorders. In the context of these diseases proteins such as BBS proteins and Rab11 play a role in mediating the effects of dysfunctional RAB8A-related pathways.
