Golgi integral membrane protein 4

Plays a role in endosome to Golgi protein trafficking; mediates protein transport along the late endosome-bypass pathway from the early endosome to the Golgi.

Phosphorylated probably by c-AMP-dependent kinases in its lumenal part.

O-glycosylated; modified by sialic acid residues.

N-glycosylated; N-glycans are probably of the complex type and modified by sialic acid residues.

Belongs to the GOLIM4 family.

• Golgi apparatus
• Golgi stack membrane
• Single-pass type II membrane protein
• Endosome membrane
• Single-pass type II membrane protein
• Membrane
• Lipid-anchor
• Localizes to cis and medial Golgi cisternae. Probably cycles between early Golgi and distal compartments like endosome.
