Nemo-like kinase 1 (Nlk1) and paraxial protocadherin (PAPC) cooperatively control Xenopus gastrulation through regulation of Wnt/planar cell polarity (PCP) signaling
Nlk1 regulates Xenopus gastrulation via PAPC-dependent Wnt/PCP control. Direct interaction of Nlk1 with PAPC stabilizes both proteins. The kinase activity of Nlk1 is not essential for the regulation of PAPC. Conserved serine residues in the PAPC C-terminus control its stability and function.
