Gene Group (FlyBase)
CYCLIN DEPENDENT KINASES -
Cyclin-dependent kinases (CDKs) are serine/threonine kinases whose activity depends on a regulatory cyclin subunit. (Adapted from PMID:25180339).
Pathway (FlyBase)
POSITIVE REGULATORS OF WNT-TCF SIGNALING PATHWAY -
Positive regulators of Wnt-TCF (canonical Wnt) signaling up-regulate the pathway, resulting in the enhancement of transcriptional regulation mediated by β-catenin (arm).
Summary (Interactive Fly)

If you don't see a structure in the viewer, refresh your browser.
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

Eip63E transcripts are detected at all stages of development on northern blots. They are found to be ubiquitous in early embryos by in situ hybridization. They are also present at a low level throughout the embryo at later stages of embryogenesis. Transient strong signals were observed in a number of tissues. These include the anterior and posterior midguts (in cells rearranging cell-cell contacts), tracheal precursors (during invagination), myoblasts (during fusion), and discrete cells of the CNS (which may be migrating glia).

        When dsRNA constructs are made and transiently transfected into S2 cells in RNAi experiments, a decrease in mitotic index is seen.

        Eip63E is required not only for metamorphosis, but also maternally and for embryonic and larval development.
