Rabproteiineissa
Rabproteiineissa are a conserved family of small GTPases that regulate vesicular transport in eukaryotic cells. They act as molecular switches controlling vesicle budding, movement, docking, and fusion across the endomembrane system. Across species, the Rab family comprises dozens of members, each associated with a particular membrane compartment.
Biochemical properties: Rabproteiineissa are approximately 20–25 kDa GTPases that cycle between a GTP-bound active state and
Function and localization: Rabproteiineissa recruit specific effectors, including tethering factors, motor proteins, and SNARE adaptors, to
Regulation and significance: Rabproteiineissa-mediated trafficking is essential for development and cellular homeostasis. Dysregulation or mutations in
