Summary: Enables Wnt-protein binding activity; frizzled binding activity; and transmembrane receptor protein tyrosine kinase activity. Involved in generation of neurons and neuroblast migration. Located in several cellular components, including dendrite; neuromuscular junction; and neuronal cell body membrane. Is expressed in several structures, including QL; head; hypodermis; neurons; and pharynx. Human ortholog(s) of this gene implicated in autosomal recessive Robinow syndrome; autosomal recessive nonsyndromic deafness 108; brachydactyly type B1; and cleft palate. Orthologous to several human genes including ROR1 (receptor tyrosine kinase like orphan receptor 1). [provided by Alliance of Genome Resources, Jan 2025]

SAX-3 binds to Wnt/CWN-2 and facilitates the membrane recruitment of CWN-2. SAX-3 forms a complex with the Ror/CAM-1 receptor and its downstream effector Dsh/DSH-1.

Loss of the Frizzled receptor LIN-17 or the planar cell polarity (PCP) protein VANG-1 also caused cross over defects that did not enhance those in the cam-1 mutant, indicating that the proteins function together in midline guidance.. Strong cam-1 expression can be detected in the PVQs and the guidepost cell PVT that is located on the midline

Study shows that CAM-1 and the Frizzled receptor MOM-5 act in parallel pathways to control the anterior polarization of the mechanosensory neuron ALM.

In a Frizzled-dependent manner, PLR-1 reduces surface levels of the Wnt receptors CAM-1/Ror and LIN-18/Ryk.

aha-1 and ahr-1 act genetically upstream of cam-1. CAM-1, a membrane-bound receptor tyrosine kinase, is present on both BDU and PLM cells and likely serves as a Wnt antagonist
Title: Neuronal target identification requires AHA-1-mediated fine-tuning of Wnt signaling in C. elegans.
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.
Title: Wnt-Ror signaling to SIA and SIB neurons directs anterior axon guidance and nerve ring placement in C. elegans.
The developmental survival of specific neurites in Caenorhabditis elegans largely depends on detection of the morphogen Wnt by the Ror kinase CAM-1.

CAM-1 extracellular domain binds to several Wnts in vitro and non-autonomously inhibits the Wnt pathway.

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.
