Required for cis-Golgi integrity and efficient ER to Golgi transport. Involved in the maintenance of the integrity of the cis-Golgi, possibly via its interaction with GOLGA2/GM130. Interacts with GOLGA2/GM130. Expressed strongly in the exocrine pancreas. The B box-type and RING-type zinc fingers although degenerate play a central role in function of the protein. Phosphorylated. Belongs to the ZFPL1 family.
