Phosphorylation of serine 68 of Twist1 stabilizes Twist1 protein and promotes breast cancer cell invasiveness.
Twist1 can be phosphorylated in vitro at Serin 68 by MAPKs (p38MAPKs, JNKs, ERK1/2)
This phosphorylation is required for Twist1 protein stability.
pSer 68 stabilizes Twist1 by protecting Twist1 from ubiquitination
Ser 68 phosphorylation is required for Twist1- promoted EMT and breast cancer cell invasion
