Gene Summary
hippo (hpo) encodes a kinase in the Salvador-Warts-Hippo pathway. It controls tissue growth by controlling cell growth, proliferation and apoptosis. It has several roles in post-mitotic cells including fate specification of photoreceptors and tiling of dendritic neurons. [Date last reviewed: 2019-03-07] (FlyBase Gene Snapshot)

Gene Snapshot

It has several roles in post-mitotic cells including fate specification of photoreceptors and tiling of dendritic neurons. [Date last reviewed: 2019-03-07]
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)
HIPPO SIGNALING PATHWAY CORE COMPONENTS -
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. Activation of the Hippo pathway results in the down-regulation of cell proliferation and up-regulation of apoptosis, limiting tissue size. (Adapted from FBrf0224870).
Protein Function (UniProtKB)
Plays a key role in the Hippo/SWH (Sav/Wts/Hpo) signaling pathway, a signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein Hippo (Hpo), in complex with its regulatory protein Salvador (Sav), phosphorylates and activates Warts (Wts) in complex with its regulatory protein Mats, which in turn phosphorylates and inactivates the Yorkie (Yki) oncoprotein. The Hippo/SWH signaling pathway inhibits the activity of the transcriptional complex formed by Scalloped (sd) and Yki and the target genes of this pathway include cyclin-E (cycE), diap1 and bantam. Phosphorylates Sav, Wts and Th/DIAP1. Regulates the level of Th/DIAP1 apoptosis inhibitor.
(UniProt, Q8T0S6)
Summary (Interactive Fly)

a serine/threonine kinase - acts in conjunction with Salvador and Warts to restrict cell growth - promotes cell death by decreasing the level of Thread, an inhibitor of apoptosis - polycomb genes interact with the tumor suppressor genes hippo and warts in the maintenance of sensory neuron dendrites

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 has been made from templates generated with primers directed against this gene.

      hpo acts cell autonomously in class IV neurons.

      hpo acts through trc and wts to regulate dendritic tiling and maintenance, respectively.

      hpo regulates expression of the ban miRNA.

      dsRNA made from templates generated with primers directed against this gene is tested in an S2 cell phosphorylation experiment to assess teh hpo signal transduction pathway.

      yki is a kinase substrate of wts, becoming phosphorylated by wts upon activation of the hpo pathway.

      When dsRNA constructs are made and transiently transfected into S2 cells in RNAi experiments, spindle abnormalities and lagging chromatids are seen.
