Figure S2. Additional TR-avidin and Lsp2 uptake data. (A-D) TR-avidin incorporation in fat body cells. Uptake is reduced in cells homozygous for Hsc70-4e3 (A) and in cells overexpressing TOR (B) or Tsc1 and Tsc2 (C). Clonal overexpression of Rheb increases uptake of TR-avidin (D). (E and F) Lsp2 staining in the fat body. Endocytosis of Lsp2 is inhibited by overexpression of Tsc1 and Tsc2 (E) and is increased in response to overexpression of Rheb (F). Clones are demarcated by GFP expression (insets) and are indicated by yellow arrows. Bar, 25 ┬Ám.
