Fig. 7. Sktl activity is required for Moesin phosphorylation.
(A,B) Immunostaining using an antibody specific for the
phosphorylated form of Moesin (P-Moe). P-Moe staining is found at the cortex
in WT Drosophila oocytes (red in A) and is abolished in
sktl2.3 mutant germline clones marked by the loss of GFP
(B). (C,D) Western blot of ovary extracts (1, 2 and 4 mean that
the equivalent of 1, 2 and 4 ovaries were loaded) from WT and
sktl2.3/sktl
5
probed with anti-P-Moe (C), anti-Moesin (D) and anti-Tubulin (
-tub) as
a loading control (C,D). (E,F) Immunostaining using an antibody
against Moesin. Moesin is localized at the cortex in both WT and
sktl2.3/sktl
5
oocytes (E,F, arrowheads). Asterisk, nucleus.
