Coatomer_g_Cpla

Coatomer_g_Cpla
PFAM accession number:PF16381
Interpro abstract (IPR032154):

This entry represents the very C-terminal domain of the eukaryotic Coatomer subunit gamma proteins. It acts as a platform domain to the C-terminal appendage. It carries one single protein/protein interaction site, which is the binding site for ARFGAP2 or ADP-ribosylation factor GTPase-activating protein. COPI-coated vesicles mediate retrograde transport from the Golgi back to the ER and intra-Golgi transport. The gamma subunit is part of one of two subcomplexes that make up the heptameric coatomer complex along with the beta, delta and zeta subunits [(PUBMED:14690497)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Coatomer_g_Cpla
