Wnt5a binds directly to the extracellular cysteine-rich domain (CRD) of Ror2, and Ror2 associates via its CRD with Frizzled2 (rFz2). Wnt5a and Ror2 together activate the non-canonical JNK pathway and inhibit convergent extension movements in Xenopus, placing Ror2 as a receptor/co-receptor for Wnt5a in non-canonical Wnt signaling. |

Ror2 associates with casein kinase Iε (CKIε) primarily via its cytoplasmic C-terminal proline-rich domain (PRD). CKIε phosphorylates Ror2 on serine/threonine residues in its ST2 domain, which in turn induces Ror2 autophosphorylation on tyrosine residues within the PRD (not the kinase domain). This CKIε-mediated activation of Ror2 then leads to tyrosine phosphorylation of GRK2 downstream. |

TAK1 (MAP3K) interacts with the intracellular domain of Ror2 and phosphorylates its C-terminal STP domain. This TAK1-dependent serine/threonine phosphorylation induces subsequent tyrosine phosphorylation of Ror2 (including a MAPK-like TGY motif) independent of Ror2's own kinase domain. A second cytosolic factor, PRTB, also interacts with Ror2 and TAK1 to enhance this phosphorylation. Wnt1 binding displaces TAK1 from Ror2, while Wnt3a and Wnt5a do not, providing ligand-dependent regulation. |

ROR2 kinase domains of human ROR1 and ROR2 are catalytically deficient (pseudokinases), in contrast to the active C. elegans ortholog CAM-1. Non-consensus residues in ROR1/2 reduce kinase activity, and restoring consensus residues does not restore robust kinase function. The membrane-bound extracellular domain alone of ROR1 or ROR2 is sufficient to suppress canonical Wnt3a signaling and enhance Wnt5a suppression of Wnt3a. |

WNT5a signaling through ROR2 activates the Hippo pathway (increasing phosphorylation of MST1/2, LATS1, MOB1, YAP1) to suppress YAP1 activity and tumor growth. Deletion of MST1/2 abrogates the WNT5a response. In ROR2-negative cells, WNT5a suppresses Hippo (via NF2/Merlin phosphorylation), revealing that ROR2 expression status determines whether WNT5a activates or suppresses Hippo. YAP1 activity also feeds back to stimulate ROR2 and WNT5a expression. |
