Overexpression of TCP20 suppresses
the actin organization defect of tor2ts
cells. Logarithmic cultures of wild-type TOR2
(JK9-3da) (A and B) and
tor2ts (SH121) cells carrying an empty vector
(C and D) or pTCP20 (pAS27) (E and
F) were grown at 30°C, shifted to 37°C for 6 h,
fixed, stained with rhodamine phalloidin, and observed by fluorescence
(A, C, and E) and Nomarski
(B, D, and F) microscopy.
tor2ts cells carrying an empty vector have a
random actin distribution.
