Is there really any evidence that Ctnnb1 is phosed on S45 by Csnk1e?

======================
Direct Phosphorylation
======================

Ctnnb1 phos by Csnk1e requires Axin1

  *** rCtnnb1[32P] phos[32P-ATP] is increased by (rCsnk1e + rAxin1(383-677))
    *** cells: none
    *** reqs: rAxin1(383-677) [omission]

Ctnnb1 phos by Gsk3b requires Axin1 and Csnk1e

  *** rCtnnb1[32P] phos[32P-ATP] is unchanged by (rGsk3b + rAxin1(383-677))

Can Csnk1e be substituted by another kinase?
