Figure 1. Rab GAP assay with AS160 GST–GAP domain and GST–Rab14.
(A) TLC separation of α32P GDP and GTP in assays with Rab14 alone, Rab14 plus the GAP domain, and Rab14 plus the R/K mutant of the GAP domain. (B) The data from (A) are presented as the percentage of the total radioactivity in GDP versus time for Rab14 (●), Rab14 plus the GAP domain (■), and Rab14 plus the R/K mutant GAP domain (▲). For further details, see the Experimental section.
