Activity summary

Rab 6A also known as Ras-related protein Rab-6A is a member of the Rab family of small GTPases and has a molecular weight of approximately 24 kDa. This protein plays an essential role in intracellular transport mechanisms particularly overseeing the trafficking of proteins and lipids between the Golgi apparatus and the endoplasmic reticulum. Rab 6A is expressed in various tissues but is found predominantly in neuronal tissues where it has vital functions.

Biological function summary

This protein is involved in regulating membrane trafficking and maintains Golgi apparatus structure. Rab 6A engages with several other proteins to form complexes necessary for the vesicular transport processes. It aids in coordinating the interactions between transport vesicles and their target membranes directly impacting cellular homeostasis and protein export.

Pathways

Rab 6A operates significantly in the secretory pathway as well as the Golgi retrograde transport pathway. Within the secretory pathway it directly affects protein sorting and recycling. Additionally Rab 6A interacts with proteins such as Bicaudal-D and dynactin which link it to the recruitment and movement of vesicular cargo along the microtubules integrating it into the broader network of intracellular pathway regulation.

Associated diseases and disorders

Rab 6A has connections with neurological conditions. Its dysfunction or misregulation can impact neurodegenerative diseases such as Alzheimer's disease by disrupting protein processing and transport. Rab 6A interacts with amyloid precursor protein-processing pathways emphasizing its role in disease pathways. Also Rab 6A is linked to disorders affecting the Golgi apparatus a critical site for protein post-translational modification and trafficking within cells.
