COG2

Conserved oligomeric Golgi complex subunit 2 is a protein that in humans is encoded by the COG2 gene. Multiprotein complexes are key determinants of Golgi apparatus structure and its capacity for intracellular transport and glycoprotein modification. Several complexes have been identified, including the Golgi transport complex (GTC), the LDLC complex, which is involved in glycosylation reactions, and the SEC34 complex, which is involved in vesicular transport. These 3 complexes are identical and have been termed the conserved oligomeric Golgi (COG) complex, which includes COG2 (Ungar et al., 2002).

Interactions
COG2 has been shown to interact with COG4 and COG3.
