In particular, coatomer complexes containing gamma1 paired with either zeta1 or zeta2 preferentially localize to the early Golgi, whereas the gamma2/zeta1 combination is predominantly found in the late Golgi. This isoform-specific distribution implies that distinct COPI vesicle populations may mediate unique functions in protein sorting and trafficking along the early secretory pathway."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "Notably, the abstract does not provide any information regarding LINC01772.
