    ..GUP1 is highly conserved among fungi and protozoa and the gup1Delta phenotype is partially corrected by GUP1 homologues of Aspergillus fumigatus and Trypanosoma cruzi. ..

    ..On theoretical grounds, we suggest that canalization of auxin flux between an auxin source and an auxin sink may involve facilitated diffusion rather than polar transport. ..

    ..Thapsigargin-induced upregulation of ERGIC-53 could be fully accounted for by the ATF6 pathway of UPR. The results suggest that in mammalian cells the UPR also affects traffic from and beyond the ER. ..
