RAB27B also known as Ras-related protein Rab-27B belongs to the Rab family of small GTPases and has a molecular mass of approximately 25 kDa. RAB27B is involved in intracellular vesicle trafficking processes. It is expressed in various tissues with notable expression in platelets and secretory cells. The protein cycles between GDP-bound inactive and GTP-bound active states regulates cargo delivery and maintains distinct cellular compartments.

Biological function summary

The functional role of RAB27B includes mediating the transport and exocytosis of secretory vesicles. This protein collaborates with effector molecules such as MLPH (melanophilin) as part of a multiprotein complex that facilitates vesicle membrane docking and fusion. RAB27B's activity ensures proper cellular secretion processes impacting hormone release pigment distribution and other essential secretory pathways.

Pathways

RAB27B participates in the exosome secretion and regulated secretory pathways. It closely interacts with other proteins including RAB27A which shares similar trafficking functions. RAB27B plays a role in specialized secretory pathways affecting the maturation and docking of vesicles in cells like melanocytes and cytotoxic T lymphocytes which are essential for efficient immune responses and pigmentation respectively.

RAB27B is relevant in conditions such as cancer and Griscelli syndrome. Its dysregulation can contribute to tumor progression and metastasis due to altered vesicle trafficking and secretion dynamics. In Griscelli syndrome type 2 mutations in the related protein RAB27A although not directly in RAB27B impact melanosome transport leading to pigmentary issues and immune dysfunction. Understanding RAB27B's involvement offers insights into potential therapeutic strategies targeting these pathways.

靶点信息

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 (PubMed : 21775604, PubMed : 30771381). RAB27B regulates homeostasis of late endocytic pathway, including endosomal positioning, maturation and secretion (PubMed : 30771381). Plays a role in NTRK2/TRKB axonal anterograde transport by facilitating the association of NTRK2/TRKB with KLC1 (PubMed : 21775604). May be involved in targeting uroplakins to urothelial apical membranes (By similarity).
