    ..These results show consistently that Sec22p recycles from the Golgi back to the ER and that this recycling involves retrograde COPI vesicles. ..

  8. Béthune J, Kol M, Hoffmann J, Reckmann I, Brugger B, Wieland F. Coatomer, the coat protein of COPI transport vesicles, discriminates endoplasmic reticulum residents from p24 proteins. Mol Cell Biol. 2006;26:8011-21 pubmed
    ..In contrast, ER-resident cargos bind to coatomer as monomers and to sites other than gamma-COP. The COPI coat therefore discriminates between p24 proteins and ER-resident proteins by differential binding involving distinct subunits. ..
  9. Matanis T, Akhmanova A, Wulf P, del Nery E, Weide T, Stepanova T, et al. Bicaudal-D regulates COPI-independent Golgi-ER transport by recruiting the dynein-dynactin motor complex. Nat Cell Biol. 2002;4:986-92 pubmed
    ..These data suggest that coordinated action between Rab6a, BICD and the dynein-dynactin complex controls COPI-independent Golgi-ER transport. ..
