Ras-related protein Rab-2

UniProtKB accession:  O18333

Grouped By:  Matching UniProtKB accession

UniProtKB description:  May be involved in bidirectional endoplasmic reticulum (ER) to Golgi trafficking (PubMed:33822845). In larval motor neurons, mediates the biogenesis of presynaptic cargo vesicles and their long-range axonal trafficking to synaptic termini (PubMed:33822845). Not involved in axonal trafficking of mitochondria (PubMed:33822845). During vesicle biogenesis, active zone proteins (including brp/Bruchpilot) and synaptic vesicle proteins (including VGlut) are sorted from the trans-Golgi in a Rab2-dependent manner via, at least, two independent routes (PubMed:33822845). Acts upstream of Arl8 during presynaptic precursor vesicle biogenesis (PubMed:33822845). Associated with lysosomal marker positive presynaptic cargo vesicles during anterograde and retrograde axonal trafficking, probably while in its GTP-bound active state (PubMed:33822845). Involved in the delivery of presynaptic cargos, but not presynapse assembly or active zone function at synaptic termini (PubMed:33822845). May be involved in the autophagic degradative pathway (PubMed:33822845).
