GOLIM4
Function
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.
Post-translational modifications
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.
Sequence Similarities
Belongs to the GOLIM4 family.
Cellular localization
- 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.
