Rab7 function
The Rab family of proteins is a member of the Ras superfamily of small G proteins. Approximately 70 types of Rabs have now been identified in humans. Rab proteins generally possess a GTPase fold, which consists of a six-stranded beta sheet which is flanked by five alpha helices. Rab GTPases regulate many steps of membrane trafficking, including vesicle formation, vesicle movement along actin and tubulin networks, and membrane fusion. These processes make up th… WebApr 6, 2024 · Although mammalian Rab7 is not essential for fusion between autophagosomes and lysosomes, it is still possible that Rab7 functions in fusion events. Two possible scenarios explain the Rab7-KO phenotype under fed conditions. The first possible scenario is that Rab7 functions in the amphisome–lysosome fusion step (Jäger …
