This structure produces a prominent clear perinuclear hof in plasma cells. GM130 is believed to assist in the assembly of this structure, which also appears to require GRASP proteins. The GRAB-domain helps localize proteins to this structure by binding to ARF1. (-5[1])This structure is the destination of (*) COPII coated vesicles, which undergo anterograde transport. Round-headed, infertile sperm form due to the inability of this organelle to develop (-5[1])into the acrosome. This organelle is the primary site of O-linked glycosylation. Proteins from the ER are transported to the cis (10[1])face of this structure in preparation for secretion. For 10 points, name this organelle that packages and modifies (10[2])proteins. ■END■ (10[1])
