Fig. 4. Coexpression of TACE and SAP97 alters their cellular distribution. COS-7
cells were transfected with different forms of haTACE and GFP-SAP97 and their
cellular distribution was analyzed. (A) GFP-SAP97 presents a distribution
similar to that of GFP-SAP97DPDZ3. (B) haTACE presents a
distribution similar to that of haTACEm. (C) Distribution of GFP-SAP97 when
coexpressed with haTACE (three representative cellular distributions are
shown). (D) Distribution of GFP-SAP97 when coexpressed with haTACEm. (E)
Distribution of GFP-SAP97DPDZ3 when coexpressed with
haTACE. Distribution of GFP-SAP97 overexpressed forms were assessed by GFP
epifluorescence with a FITC filter. TACE overexpressed forms were detected
using anti-HA epitope antibodies followed by Rhodamine-conjugated secondary
antibodies and their distributions revealed by Rhodamine epifluorescence.
