Contents 1 Function 2 Structure 3 Compartment 4 More General Terms 5 Internet Database 6 References

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
• phosphorylated by c- AMP-dependent kinases in its lumenal part ( putative)

Structure

• O-glycosylated, modified by sialic acid residues
• N-glycosylated, N-glycans are probably of the complex type & modified by sialic acid residues
• belongs to the GOLPH4 family

Compartment

• Golgi membrane, endosome membrane
• localizes to cis & medial Golgi cisternae
• probably cycles between early Golgi & endosome

More General Terms

• membrane protein
• glycoprotein
• phosphoprotein
