    Summary
    Enables ubiquitin binding activity. Involved in endoplasmic reticulum to Golgi vesicle-mediated transport; intracellular mRNA localization; and retrograde vesicle-mediated transport, Golgi to endoplasmic reticulum. Part of COPI vesicle coat. Orthologous to human COPA (COPI coat complex subunit alpha). [provided by Alliance of Genome Resources, Apr 2022]

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. 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.
    2. 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.
    3. 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.
    4. 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.
