Summary: Enables cell adhesion molecule binding activity and epidermal growth factor receptor binding activity. Involved in several processes, including morphogenesis of an epithelium; negative regulation of cell differentiation; and regulation of signal transduction. Located in several cellular components, including adherens junction; cell surface; and early endosome. Is expressed in several structures, including epithelium; follicle cell; gut section; head epidermis primordium; and somatic precursor cell. [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Together, our results demonstrate that transcriptional repression of Ed followed by Smurf-mediated downregulation of pretranslated Ed in amnioserosa regulates the establishment of a taut leading edge during dorsal closure
Title: Smurf Downregulates Echinoid in the Amnioserosa To Regulate Drosophila Dorsal Closure.
Data propose that Ed-mediated cell sorting is driven both by differential Ed adhesion that induces cell segregation with a jagged border and by actomyosin cable assembly at the interface that smoothens this border.
Title: Differential adhesion and actomyosin cable collaborate to drive Echinoid-mediated cell sorting.
The planar polarized distribution of Echinoid in the DME cells thus provides a spatial cue that polarizes the DME cell actin cytoskeleton, defining the epidermal leading edge and establishing its contractile properties.
Title: Asymmetric distribution of Echinoid defines the epidermal leading edge during Drosophila dorsal closure.
Data show that tracheal-specific expression of Echinoid rescues cell fusion defects, indicating that Ed acts in the trachea to control fusion cell fate.
Title: Echinoid regulates tracheal morphology and fusion cell fate in Drosophila.
Co-endocytosis of Ed and Fmi provides a link between apicobasal polarity and planar cell polarity.
Title: Echinoid regulates Flamingo endocytosis to control ommatidial rotation in the Drosophila eye.
differential levels of Ed and Fred between stationary and rotating cells at the initiation of rotation create a permissive environment for cell movement, and uniform levels in these two populations later contribute to stopping the movement
Title: The cell adhesion molecules Echinoid and Friend of Echinoid coordinate cell adhesion and cell signaling to regulate the fidelity of ommatidial rotation in the Drosophila eye.
Data suggest that Echinoid mediates the dimerization of myosin VI/Jaguar in vivo which in turn regulates the reorganization and/or contraction of actin filaments to control changes in cell shape.
Title: Cell adhesion molecule Echinoid associates with unconventional myosin VI/Jaguar motor to regulate cell morphology during dorsal closure in Drosophila.
antagonizes the bristle-promoting activity of the Egfr pathway, either by the enhancement of Notch signalling or, similar to the eye, by a more direct action on the Egfr pathway
Title: Echinoid synergizes with the Notch signaling pathway in Drosophila mesothorax bristle patterning.
role of Ed during embryonic nervous system development, as well as adult sensory bristle specification; interacts synergistically with the Notch signaling pathway
Title: Echinoid mutants exhibit neurogenic phenotypes and show synergistic interactions with the Notch signaling pathway.
results suggest a model in which neuroglian acts as a heterophilic ligand and activator of echinoid, which in turn antagonizes EGFR signaling
Title: Neuroglian activates Echinoid to antagonize the Drosophila EGF receptor signaling pathway.
