Facts about Ras-related protein Rab-5A.
RAB5A is required for the fusion of plasma membranes and early endosomes (PubMed:10818110, PubMed:14617813, PubMed:16410077, PubMed:15378032). Contributes to the regulation of filopodia extension (PubMed:14978216).

What are the most effective uses of the RAB5A antibody? Boster Bio produces antibodies for all kinds of biological applications. The validation process involves comparing known positive samples against negative ones to ensure high specificity. Boster gives the first reviewer of a new product with a certificate for the review, which is useful to scientists world-wide. However, the question remains: Are antibodies really necessary?
The RAB5A marker which is extremely specific to mitochondrial proteins is extremely specific. When cells are injured, they attempt to repair mitochondria by creating MDVs. However, severe damage is able to lock the entire mitochondrion inside an early endosome with a Rab5-positive gene. The RAB5A marker is essential for detecting cell damage. Boster Bio has developed high-affinity antibodies that are available for various applications.
The RAB5A marker is extremely sensitive and is able to detect endosomal as well as Lysosome bound Rab5 proteins. It is able to identify endosomes that contain Rab5GTP due to its affinity to Rab5GAP5. The RAB5A marker can detect endosomal Rab5-GTP by co-localizing with RabGAP5. In this study, depletion of DRG2 did not affect Rab5-GAP5 co-localization.
Bostro Bio validated the RAB5A marker. This is a further proof of its credibility. In Rab5 endosomes, there is the Rab5 protein complex which comprises Ulk1, TrkA and Rab5. The inability to inhibit Rab5 activity results in the misdirected signaling between these proteins, which results in neurodegeneration. The RAB5A marker thus provides an effective tool for detecting the presence of abnormalities in Rab5 activity.
Validation of the RAB5A marker has revealed that this protein complex controls both the endocytic process and the transportation of TrkA and NGF. Two distinct populations of Rab5 positive endosomes exist, one that is dynamic and one static. They are slow to mature and have limited mobility. The latter are similar to Rab5-S34N-positive structures, displaying localized movement and interaction with TrkA.
