List of She-localized mRNAs. Also indicated are whether each transcript is cell cycle-regulated and its peak stage (49, 50), the predicted or known function, and protein localization of each. Proteins that are asymmetrically enriched in the bud are indicated by boldface. The full list of transcripts assayed for localization as well as their percentile rankings from microarray analysis can be viewed in Table 2. Full array results and additional methodology can be viewed in Supporting Materials and Methods and at http://valelab.ucsf.edu/~shepard/methods.html or http://genome-www5.stanford.edu/MicroArray/SMD/.C, carboxyl terminus; N, amino terminus. Yes, ≥90% bud localization; Partial, 50-60% localization; Weak, 15-30% localization; No, unlocalized (<5% localization; ND, not determined).
