Describe the exocytosis pathway of this protein

Protein “Z” is a highly glycosylated phosphoprotein. This protein is known to be produced by fibroblasts and is present abundantly in the extracellular matrix (ECM) of the periodontal ligament (PDL). Describe the exocytosis pathway of this protein: from the site at which it is made to the place (i.e., ECM of the PDL) in which it is primarily present. Describe all of the possible steps this protein my go through before it reach the ECM of the PDL. Also discuss about in which compartments the glycosylation and phosphoryaltion of this protein may take place.
