Plasma membrane externalization of TRPC3 detected by cell surface
biotinylation. Cell surface biotinylation was performed with HEK 293T
cells expressing V5-TRPC3, V5-TRPC3-DEL, V5-TRPC3-SUB, or V5-TRPC3-F4 and
Epo-R. Lysates were prepared, and immunoprecipitation (IP) was
performed with anti-V5 antibody. Western blotting (WB) was performed
on immunoprecipitation pellets with streptavidin-HRP to detect biotinylation
and anti-V5-HRP to detect total TRPC3. Representative results of two
experiments are shown. Tx'd, transfected.
