What's a GeneRIF?

These results indicate that ubiquitination, a modification well known to target membrane proteins to the lysosome or vacuole for degradation, can also function as recycling signal to sort a SNARE into COPI vesicles in a non-degradative pathway.
Title: COPI mediates recycling of an exocytic SNARE by recognition of a ubiquitin sorting signal.
These findings suggest that cisternal maturation involves a COPI-dependent pathway that recycles early Golgi proteins, followed by multiple COPI-independent pathways that recycle late Golgi proteins.
Title: COPI selectively drives maturation of the early Golgi.
analysis of the structure of alpha-COP in complex with epsilon-COP provides insight into the architecture of the COPI vesicular coat
Title: Crystal structure of alpha-COP in complex with epsilon-COP provides insight into the architecture of the COPI vesicular coat.
COPI in these mutants is released from Golgi membranes by brefeldin A, a drug that binds directly to guanine nucleotide exchange factor for ADP-ribosylation factor ribosylation factors and blocks Arf1 activation
Title: Mutations in a highly conserved region of the Arf1p activator GEA2 block anterograde Golgi transport but not COPI recruitment to membranes.
