Table II.
Identification of small GTP-binding proteins
SID (sequence ID) represents arbitrary values differentiating indiscernible protein sets; GID (global ID) represents indiscernible protein group identifier; CID (cluster ID) represents protein groups that have common peptides (in the supplemental table, these identifiers are hyperlinked to their IDPicker Web pages); Unique peptides is the total number of unique peptides that were identified. Spectra lists the total number of spectra in the three independent experiments: Exp1/G8 (Experiment 1), Exp2/4t (Experiment 2), and Exp3/G10 (Experiment 3). Acc/ID indicates other accession numbers and IDs. Numbers in the last column are the references reporting a link to basolateral trafficking.
