  • "We were not able to colocalize DrpB with markers of the secretory pathway, such as the cis-medial Golgi marker GRASP-RFP [20], the trans-Golgi marker UDP-N-acetyl-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase T1 fused to yellow fluorescent protein (YFP) (TgGalNac-YFP; M. Nishi and D.S. Roos, personal communication) [4], the propeptide of M2AP (a precursor microneme protein that localizes in endosome-related compartments) [4], VP-1 (a vacuolar proton pyrophosphatase) [4], or the μ1 chain of the adaptin-1 complex 3."

golgi apparatus and limiting membrane of rhoptry and luminal membrane of rhoptry and multi-vesicular endosome and trans-golgi network during tachyzoite
  • "The T. gondii AP-1 adaptin complex is implicated in this transport because the micro1 chain of T. gondii AP-1 (a) was localized to multivesicular endosomes and the limiting and luminal membranes of the rhoptries; (b) bound to endocytic tyrosine motifs in rhoptry proteins, but not in proteins from dense granule secretory organelles; (c) when mutated in predicted tyrosine-binding motifs, led to accumulation of the rhoptry protein ROP2 in a post-Golgi multivesicular compartment; and (d) when depleted via antisense mRNA, resulted in accumulation of multivesicular endosomes and immature rhoptries. ... Tgµ1 is predominantly localized to the Golgi/TGN as indicated by immunofluorescence microscopy."
