  • a The pK15-interacting proteins identified from cells treated with a reactivation cocktail (RTA plus SB) was processed similarly to those in Table 1, and the resulting list of proteins is shown here. Proteins annotated to be involved in the endocytic pathway by using the DAVID bioinformatics tool are in boldface type. FE, fold enrichment.
