CC -!- FUNCTION: Involved in protein trafficking vesicle formation, probably
CC by stabilizing of coatomer at the Golgi membrane and thus allowing the
CC efficient formation of COPI coated vesicles.
CC {ECO:0000269|PubMed:12925749}.
CC -!- SUBUNIT: Interacts with MST28. Binds to coatomer proteins of COPI and
CC SEC23/SEC24 of COPII coated vesicles. {ECO:0000269|PubMed:12925749}.
CC -!- INTERACTION:
CC P53176; P39552: MST28; NbExp=4; IntAct=EBI-6205, EBI-20785;
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum
CC {ECO:0000269|PubMed:12101299, ECO:0000269|PubMed:12925749}. Golgi
CC apparatus {ECO:0000269|PubMed:12925749}. Cytoplasmic vesicle, COPI-
CC coated vesicle membrane {ECO:0000269|PubMed:12925749}; Multi-pass
CC membrane protein {ECO:0000269|PubMed:12925749}. Cytoplasmic vesicle,
CC COPII-coated vesicle membrane {ECO:0000269|PubMed:12925749}; Multi-pass
CC membrane protein {ECO:0000269|PubMed:12925749}.
CC -!- MISCELLANEOUS: Members of the DUP240 multigene family are specific to
CC S.cerevisiae sensu strictu. Cells lacking all 10 DUP240 proteins show
CC no obvious alterations in mating, sporulation and cell growth.
CC -!- SIMILARITY: Belongs to the DUP/COS family. {ECO:0000305}.
