text
| VAMP3 and VAMP7 colocalize with the major myelin proteolipid protein (PLP1) in recycling endosomes and late endosomes/lysosomes, respectively |
|
ANKRD27, VAMP7 and RAB21 co-localize in the perinuclear region of differentiating hippocampal neurons and transiently in transport vesicles in the shaft of neurites |
|
localizes to endosomes and lysosomes but also to the trans-Golgi network |
|
localizes to melanosomes and is required for pigmentation and cargo trafficking |
basic FUNCTION
| soluble N ethylmaleimide-sensitive factor-attachment protein receptor |
|
required with VAMP8 for activation-induced degranulation of mature mast cells |
|
enriched in intestinal ER and that it plays a functional role in the delivery of triacylglycerol from the ER to the Golgi |
|
mediates exocytosis during neuritogenesis, phagocytosis and lysosomal secretion |
|
role in the secretory pathway of a tetraspanin |
|
adopts a preferentially closed conformation in solution |
|
with other VAMPs, has differential membrane fusion capacities, and imply that with the exception of VAMP5, VAMPs are essentially redundant in mediating fusion with plasma membrane t-SNAREs |
|
involvement of VAMP3/cellubrevin and VAMP7/TI-VAMP in myelin membrane trafficking |
|
controls exocytosis of PLP1 from late endosomal/lysosomal organelles as part of a transcytosis pathway) |
|
involved in multiple cell pathways, including control of neurite outgrowth |
|
required in neurons to extend axons to the full extent |
|
associates with perforin-containing granules in nonactivated cells, indicating that the two VAMPs have different functions in exocytosis |
|
involved in many fusion processes and thus plays a more general function in NK-cell activity than VAMP4 |
|
unexpected role of VAMP7-mediated vesicular traffic in anxiety, suggesting a role for VAMP7 in higher brain functions |
|
VPS41 and VAMP7 are specifically involved in the fusion of trans-Golgi network-derived lysosome-associated membrane protein carriers with late endosomes |
|
role for VAMP7 in pigmentation by trafficking melanosomal cargoes such as TYRP1 from endosomes to maturing melanosomes |
|
VAMP7 and TYRP1 traffic to melanosomes in BLOC1S1–dependent membrane tubules |
