Official Symbol: lin-18
Official Full Name: Inactive tyrosine-protein kinase RYK
Primary source: WormBase:WBGene00003007
Locus tag: CELE_C16B8.1
See related: AllianceGenome:WB:WBGene00003007
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)
Lineage: Eukaryota; Metazoa; Ecdysozoa; Nematoda; Chromadorea; Rhabditida; Rhabditina; Rhabditomorpha; Rhabditoidea; Rhabditidae; Peloderinae; Caenorhabditis
Summary: Predicted to enable transmembrane receptor protein tyrosine kinase activity. Involved in several processes, including asymmetric protein localization involved in cell fate determination; axis specification; and positive regulation of axon guidance. Located in cytoplasm; nucleus; and plasma membrane. Is expressed in body wall musculature; neurons; vulva; and vulval precursor cell. Orthologous to human RYK (receptor like tyrosine kinase).

What's a GeneRIF?

Ryk-intracellular domain fragment suppressed neuroprotection by lin-18/Ryk loss-of-function in expanded-polyQ nematodes, repressed FOXO transcriptional activity, and abolished beta-catenin protection of mutant htt striatal cells against cell death
Title: The Wnt receptor Ryk reduces neuronal and cell survival capacity by repressing FOXO activity during the early phases of mutant huntingtin pathogenicity.
Release of LIN-18ICD by cleavage at the membrane is not the main mechanism of LIN-18 signaling in vulval cells. results suggest LIN-18 intracellular domain interacts with Wnt pathway and a 14-3-3 protein and likely plays a minor role in LIN-18 signaling

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

ceMIB (Caenorhabditis elegans Mindbomb/Y47D3A.22) plays a role in the regulation of C. elegans Wnt/RYK (lin-18) /TCF signaling.
Title: Mindbomb 1, an E3 ubiquitin ligase, forms a complex with RYK to activate Wnt/β-catenin signaling.
LIN-18 encodes a member of the Ryk/Derailed family of tyrosine kinase-related receptors, recently found to function as Wnt receptors. Members of this family have nonactive kinase domains
Title: C. elegans LIN-18 is a Ryk ortholog and functions in parallel to LIN-17/Frizzled in Wnt signaling.
lin-17 (Frizzled type Wnt receptor) and lin-18 (Ryk) regulate the pattern of POP-1 localization and cell type specification in the posterior half of the vulva.
