  1. Kim C, Forrester W. Functional analysis of the domains of the C elegans Ror receptor tyrosine kinase CAM-1. Dev Biol. 2003;264:376-90 pubmed
    ..Our results show that CAM-1 does not function exclusively as a canonical RTK and that it may function, at least in part, to regulate the distribution of a secreted ligand-possibly a Wnt protein. ..
  2. Green J, Inoue T, Sternberg P. The C. elegans ROR receptor tyrosine kinase, CAM-1, non-autonomously inhibits the Wnt pathway. Development. 2007;134:4053-62 pubmed
    ..A sequestration model is supported by our findings that the CAM-1 ECD binds to several Wnts in vitro. These results demonstrate how ROR proteins help to refine the spatial pattern of Wnt activity in a complex multicellular environment...
  3. Forrester W, Kim C, Garriga G. The Caenorhabditis elegans Ror RTK CAM-1 inhibits EGL-20/Wnt signaling in cell migration. Genetics. 2004;168:1951-62 pubmed
    ..The reversal in the migration of the left Q neuroblast and its descendants resulted from a failure to express mab-5, an egl-20 mutant phenotype. Our data suggest that CAM-1 negatively regulates EGL-20. ..

    ..These results reveal the trophic role of an atypical Wnt pathway and reinforce the classical model of developmental pruning. ..

    ..Cell-specific rescue of cam-1 and cell ablation experiments reveal a crucial role for the SIA and SIB neurons in positioning the nerve ring, linking Wnt signaling to specific cells that organize the anterior nervous system. ..
  6. Forrester W, Dell M, Perens E, Garriga G. A C. elegans Ror receptor tyrosine kinase regulates cell motility and asymmetric cell division. Nature. 1999;400:881-5 pubmed
    ..Our results raise the possibility that Ror kinases regulate cell motility and asymmetric cell division in organisms as diverse as nematodes and mammals. ..

    ..Finally, we find striking differences between the phenotypes of the Wnt quintuple and Frizzled quadruple mutants. ..

    ..Our study reveals a Wnt-dependent fine-tuning mechanism that is crucial for mutual target cell identification during the formation of gap junction connections. ..

    ..In this model, loss of CAM-1 results in increased levels of Wnts that act through other Wnt receptors, masking CAM-1's autonomous role as a Wnt receptor. ..
