Summaries
Gene Snapshot
Ret oncogene (Ret) encodes a cell surface receptor mediating dendrite development of class IV dendritic arborization sensory neurons. It interacts with integrins and mediates rac1 signaling to promote dendrite adhesion to the extracellular matrix. [Date last reviewed: 2019-03-14]
(Alliance, FBgn0011829 )
Gene Group (FlyBase)
CADHERINS -
The cadherin superfamily represent a diverse group of transmembrane receptors which mediate cell-cell adhesion. Cadherins are defined by the presence of cadherin domains, typically organised in tandem repeats, which mediate calcium-dependent homophilic interactions between cadherin molecules. (Adapted from FBrf0146675).
RECEPTOR TYROSINE KINASES -
Receptor tyrosine kinases (RTK) are single-pass transmembrane receptors expressed on the plasma membrane. Upon the binding of an extracellular signalling molecule (e.g. growth factors, hormones), RTKs dimerize leading to the activation of the intracellular tyrosine kinase domain and intermolecular phosphorylation. The phosphotyrosines function as specific sites for the assembly, phosphorylation and activation of downstream signaling molecules. (Adapted from PMID:20602996).

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Additional Descriptive Data

Ret transcript is expressed in the three migrating stomatogastric nervous system precursor cell clusters from embryonic stage 13-15; expression is reduced at the end of SNS migration. Ret is also expressed at the ventral midline of the embryonic CNS, and in a few cells in the developing anterior midgut. At late embryonic stages, Ret transcript is expressed in some cells of the esophagael and proventricular ganglia, in the midgut, and at the CNS midline.

Ret transcript is expressed in small clusters of cells at the midline of the ventral neve cord segments. In third instar larva, expression is detected in a small cell cluster in the posterior ventral nerve cord.

Ret transcript is first observed at embryonic stage 8, localized to intensely-stained irregularly shaped patches in the yolk sac; these patches are interior to all three germ layers, and do not overlap with the amnioserosa. This pattern continues through embryonic stage 11, and rapidly disappers at stage 12, as the germband retracts and organogenesis begins. Ret transcript is expressed in the Malpighian tubule primordium at embryonic stage 12, but vanishes from that tissue by stage 13. Ret is also expressed in the stomatogastric nervous system and in midgut imaginal islands from stage 12 and in the peripheral nervous system of the head from embryonic stage 16, and in isolated cells in the ventral nerve cord from stage 12. In the third instar larval eye-antennal imaginal disc, expression is detected in the retinal cluster near the morphogenetic furrow, and in the ocellar region. During oogenesis, expression is detected in nurse cells, but not in mature oocytes.

Ret transcript is detected at low levels in embryonic stages, and at very low levels in larvae and pupae. Embryonic expression is first detected after cellularization, and is transient. Expression reappears in a subset of neuroblasts at embryonic stage 11, and disappears at germ band retraction. Starting at stage 13-14, three rows of cells in the ventral nerve cord express Ret transcript. Transient expression is detected at stage 13 in some PNS cells, and some ganglial cells.

Ret codes for a transmembrane protein most similar in sequence to a mammalian proto-oncogene ret. Ret mRNA is transcribed in very small amounts in the embryonic, larval and pupal stages. mRNA is transiently expressed in neuroblasts in early embryos and is detected in subpopulations of differentiating PNS and CNS cells in late embryos.
