Functions
- retrograde transport, endosome to Golgi
GO:0042147— GARP is a Golgi-localized tethering complex required for retrograde transport from early and late endosomes back to the trans-Golgi network.GO:0042147GO:0042147 denotes vesicle-mediated retrograde transport from endosomes back to the trans-Golgi network.DOI:10.1091/mbc.e02-10-0654Conibear, Cleck and Stevens 2003 found that all four yeast GARP members are required for retrograde transport from early and late endosomes back to the trans-Golgi network.
Mechanism graphs
GARP supports yeast endosome-to-Golgi retrograde transport (FUNCTION)
In Saccharomyces cerevisiae, Vps51 joins Vps52, Vps53 and Vps54 to form the GARP complex, a trans-Golgi-network tethering complex that links retrograde endosome-to-Golgi transport to the t-SNARE Tlg1p.

Discussions
- CURATION_TODO (OPEN): Resolve exact source-neutral InterPro, Pfam, or Complex Portal groundings for the four GARP subunit classes. The yeast literature names the Vps51/Vps52/Vps53/Vps54 proteins as GARP subunits, but this pass did not verify exact taxon-neutral family identifiers for those subunit classes.
- CURATION_TODO (RESOLVED): Do not model Tlg1p as a constituent GARP component. Tlg1p links to GARP through Vps51, but the canonical GARP constituent list is Vps51, Vps52, Vps53 and Vps54.
