FIGURE 3:
Tyrosine phosphorylation of TRPC6 in living cells and kidney glomeruli. (A) Lysates from HEK293T cells transfected with the indicated plasmids were probed with α-pY31 or α-pY284 antibody. (B) HEK293T cells expressing HA-TRPC6 were stimulated by EGF. α-HA immunoprecipitates were probed with α-phosphospecific TRPC6 antibodies. (C) Isolated rat glomeruli treated with or without 1 mM sodium vanadate for 30 min were blotted with α-pY284. For the indicated samples, glomeruli were pretreated with 10 mM PP2 for 15 min or 5 mM SU6656 for 60 min before treatment with vanadate.
