    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • potentially involved in peripheral nerve repair
  • inducer of apoptosis
  • canonical signaling receptor for glial cell line-derived neurotrophic factor (GDNF), having neuroprotective effects when administered prior to neurotoxic challenge
  • RET signaling is protective for dopaminergic cell bodies but not for axonal terminals
  • having a critical role in the development of the enteric nervous system (ENS), parasympathetic nervous system and kidney
  • functional role of RET51/FKBP4 complex in dopaminergic neurons and possibly in the pathogenesis of Parkinson disease
  • its expression in dorsal root ganglion neurons is crucial for the neurturin-mediated formation of precise axonal projections in the central nervous system
  • after ligand binding induces dimerization, activates multiple signal transduction pathways
  • important role of intracellular trafficking in modulating and maintaining RET signaling
  • playing a key role during embryogenesis and in particular during the enteric nervous system development
  • putative functional role of the RET gene in modulating immune cell responses during inflammation and carcinogenesis
  • activation of RET results in improved haematopoietic stem cell survival, expansion and in vivo transplantation efficiency
    receptor tyrosine kinase pathway
    a component
  • component of glial cell line derived neurotrophic factor (GDNF) receptor, homodimerizing and binding the GDNF-GFRA complex
    small molecule
  • interacting with SHC1 transduction adaptor protein
  • interacting with GDNF and GFRA1, by its extracellular domain
  • CD2AP, an adaptor molecule involved in the internalization of ubiquitinated RTKs, is associated with RET under basal, unstimulated conditions in neurons
  • CBLC interacts with unphosphorylated RET and dissociates from RET after RET activation
  • transcriptional target of NR4A2
  • involvement of a novel interaction of RET with RAP1GAP in the regulation of GDNF-mediated neurite outgrowth
  • interacting with ITGB1 (can activate ITGB1, and that RET-induced cell adhesion and migration require ITGB1)
  • caspase cleavage of RET is involved in the regulation of adhesion in sympathetic neurons
  • HOXB5 binds to the promoter region 5prime upstream of the binding site of NKX2-1 and regulates RET expression
  • HOXB5 in coordination with other transcription factors mediates RET expression
  • GDNF restores human blood-nerve barrier function via RET tyrosine kinase-mediated cytoskeletal reorganization
  • TOP2A, TOP1 are involved in initiating aphidicolin-induced common fragile site breakage at RET, and may engage the recognition of DNA secondary structures formed during perturbed DNA replication
  • PDLIM7 is a CBLC interacting protein, and binding of PDLIM7 to RET prevents CBLC recruitment to RET
  • HOXB5 regulates RET transcription, and perturbations in transcriptional regulation by HOXB5 caused reduced RET expression and defective enteric nervous system development
  • low-frequency alterations such as EIF4G1 might participate in RET-associated tumorigenesis, possibly by regulating the activity of the RET pathway
  • dual kinase function of the RET proto-oncogene negatively regulates ATF4-mediated apoptosis
  • interaction between the atypical cadherin FAT4 and RET, a tyrosine kinase receptor essential for kidney development
  • cell & other
    induced by by NR4A2 (induced the transcription of the RET promoter in cell type and concentration-dependent manner)
    inhibited by pro-apoptotic effect inhibited by its ligand GDNF
    Other regulation by acidification of the Golgi apparatus that is crucial for maturation of RET but not indispensable for trafficking of receptors to the membrane
    dys-regulation of RET expression by HOXB5 could result in insufficient RET expression and Hirschsprung disease
