Fig. 8. Dpr synergy requires CK1
or CK2. (A) Dvl2 or ß-catenin
activation of canonical target genes does not require CK1
, but Dvl2-CK2
synergy does require CK1
. Lanes 1 and 2, 0.4 ng of dvl2, 1 ng
of ck2
and 1 ng of ck2ß RNA; lanes 3 and 4, 0.8
ng dvl2 RNA; lanes 5 and 6, 0.1 ng stabilized ß-catenin RNA. (B)
Dpr1-Dvl2 and Dpr1-Par1 synergy requires CK1
, but Dpr1-CK2 synergy does
not. The amounts of RNA injected were 1 ng of dpr1, 1 ng of
par1, 0.4 ng of dvl2, 1 ng of ck2
and1 ng of
ck2ß. CKI-7 (5 nl of 2.5 mM) was co-injected in experiments in A
and B. (C) Table of Dpr1 synergistic interactions and requirement on
CK1
. Asterisk indicates higher doses of Dvl2 RNA that could activate
alone did not require CK1
, but Dvl2-CK2 synergy did require
CK1
.
