misshapen (msn) encodes a Sterile 20 MAP kinase kinase kinase. [Date last reviewed: 2019-03-14]
Gene Group (FlyBase)
GERMINAL CENTER KINASES -
Germinal center kinases (GCKs) are serine/threonine kinases characterised by an N-terminal STE20 kinase domain. They have diverse roles in signaling pathways; some are MAPK kinase kinase kinases, activating MAPK kinase kinases. (Adapted from FBrf0225276 and FBrf0228279).
Pathway (FlyBase)
POSITIVE REGULATORS OF HIPPO SIGNALING PATHWAY -
The Hippo signaling pathway is an intracellular kinase cascade in which hpo kinase in complex with sav, phosphorylates wts kinase which, in turn, phosphorylates yki transcriptional co-activator leading to its cytosolic retention. Positive regulators of the pathway, enhance the cytosolic retention of yki, negatively regulating tissue growth (Adapted from FBrf0224870).
NEGATIVE REGULATORS OF NOTCH SIGNALING PATHWAY -
The Notch receptor signaling pathway is activated by the binding of the transmembrane receptor Notch (N) to transmembrane ligands, Dl or Ser, presented on adjacent cells. This results in the proteolytic cleavage of N, releasing the intracellular domain (NICD). NICD translocates into the nucleus, interacting with Su(H) and mam to form a transcription complex, which up-regulates transcription of Notch-responsive genes. Negative regulators of the pathway down-regulate the signal from the sending cell or the response in the receiving cell. (Adapted from FBrf0225731 and FBrf0192604).
TNFalpha-EIGER SIGNALING PATHWAY CORE COMPONENTS -
The Tumor Necrosis Factor α (TNFα) signaling pathway is activated by Eiger (egr) binding to a member of the TNF receptor superfamily. The signal is primarily transduced via the Jun N-terminal kinase (JNK) cascade, leading to cell death. (Adapted from FBrf0225608.)
Summary (Interactive Fly)

Ste20-like kinase - conveys Rac signals to Basket/Jnk during dorsal closure - TIPE family member Sigmar interacts with Misshapen and modulates JNK signaling, cytoskeletal remodeling and autophagy.

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.

        dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

        msn acts through bsk in epithelial planar polarity (EPP) signalling.

        msn acts downstream of fz and dsh in the epithelial planar polarity (EPP) signalling pathway in eyes and wings.

        msn is required for the proper targetting of the R1-R6 photoreceptor cell growth cones in the developing visual system.

        Identification: Enhancer trap expression pattern survey for loci expressed in the ring gland.

        msn functions upstream of hep and bsk to stimulate dorsal closure in the embryo.

        Identification: Enhancer trap screen designed to discover genes involved in the cellular aspects of defense mechanisms, as well as in melanotic tumor formation processes linked to blood cell dysregulation.

        msn is required for the normal shape and orientation of photoreceptor cells and is essential for oogenesis. msn may act in a signal transduction pathway leading to cytoskeletal rearrangements.

        The autosomal "FLP-DFS" technique (using the P{ovoD1-18} P{FRT(whs)} P{hsFLP} chromosomes) has been used to identify the specific maternal effect phenotype for the zygotic lethal mutation.
