  • a Upper numbers are the slope b, those below are the ratio of relative surface expression in transfected to nontransfected cells. For more details see the Results and Methods sections.

  • b All listed clones, except AL713668, which is predicted to be involved in secretory membrane transport, are novel and do not contain predictable signal peptides.

  • c All clones exist in two variants: CFP fused to the N-terminus and YFP fused to the C-terminus.

  • d Clone IDs used by http://gfp-cdna.embl.de/ (upper line) and http://www.dkfz-heidelberg.de/LIFEdb (lower line) databases, respectively.

  • e Average value derived from independent experiments. For more details see Methods.

  • f standard error value derived from independent experiments. For more details see Methods.

  • g % of similarity on amino acid level derived by using “BLAST 2 sequences” program.

  • h Not determined.

  • i Change of average intensity or number of Golgi fragments. For more details see Methods.

  • j Name of yeast ORF as assigned by SGD Yeast Database.
