C-terminal truncation of Lck does not impair tethering to the plasma
membrane. 3T3-FynT cells infected with either empty Migr1 vector
(0) or vector containing either WT Lck, Y505F Lck,
ΔQPY505F, ΔQPQPY505F, or ΔFQPQP were
probed with anti-Lck (green) and anti-Fyn (red). One
representative image of each infectant is shown. The nucleus was stained with
4′,6-diamidino-2-phenylindole (blue). (×400 zoom).
