Gene Group (FlyBase)
UNCLASSIFIED AGC KINASES -
This group comprises AGC kinases that do not classify under other groups in FlyBase.
Pathway (FlyBase)
INSULIN-LIKE RECEPTOR SIGNALING PATHWAY CORE COMPONENTS -
The Insulin-like Receptor (IR) signaling pathway in Drosophila is initiated by the binding of an insulin-like peptides to the Insulin-like receptor (InR). (Adapted from FBrf0232297, FBrf0230017 and FBrf0229989.)
PVR SIGNALING PATHWAY CORE COMPONENTS -
PDGF/VEGF (Platelet-Derived Growth Factor/Vascular Endothelial Growth Factor)-receptor related (Pvr) encodes a receptor tyrosine kinase activated by the binding of PDGF- and VEGF-related factors (Pvf1,Pvf2 or Pvf3). Pvr has been shown to activate the canonical Ras/Raf/MAP kinase (ERK) cascade, the PI3K kinase pathway, TORC1 (FBrf0222697), Rho family small GTPases (FBrf0221764, FBrf0180198) and the JNK cascade (FBrf0180198), in a context-dependent manner. (Adapted from FBrf0222697 and FBrf0221727).
Summary (Interactive Fly)

signaling - regulates growth response - targets ribosomal protein S6 - a target of the TOR pathway - essential for Myc-dependent rDNA transcription

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.

Comments

Two peaks of S6 kinase activity were observed in

S2 cells, one of which is rapamycin sensitive. The cloned S6k was shown

to have identity with the rapamycin sensitive form.

        S6k plays a negative role for autophagy in normal conditions. When starvation induces autophagy, S6k may act as a positive regulator of autophagy.

        dsRNA made from templates generated with primers directed against this gene results in an immediate reduction in cell size. Silencing both eIF-4E and S6k together does not reduce mean cell diameter to the same extent as rapamycin treatment.

        S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.

        dsRNA made from templates generated with primers directed against this gene used to treat S2 cells.

        dsRNA made from templates generated with primers directed against this gene increases Akt1 phosphorylation in S2 cells.

        When dsRNA constructs are made and transiently transfected into S2 cells in RNAi experiments, an increase in the proportion of G1 phase cells is seen.

        Loss of S6k causes failure to induce autophagy under fed or starvation conditions or in reponse to loss of Tor. Activation of S6k does not affect autophagy induction in wild type, but increases the level of autophagy in Tor mutants.

        Promotes starvation-induced autophagy in the fat body.

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

        RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a phenotype when assayed in Kc167 and S2R+ cells: increased or polarized (uneven) accumulation of F-actin.

        Pk61C is an upstream effector of S6k.

        Identified as a gene with significant level of mRNA cycling as assessed by expression analysis using high density oligonucleotide arrays with probe generated from adult heads harvested over six time points over the course of a day.

        The S6k gene product regulates cell size in a cell-autonomous manner without impinging on cell number.

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

        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. S6k is required for germ cell viability or early oogenesis.

        Isolated using a rat p70s6k fragment as a probe.

        S6k has been cloned and sequenced.

        Isolated from a cDNA library using rat p70S6k cDNA sequences as a probe, under low stringency conditions.

        Isolated from a genomic library using a Pka-C1 probe.

        Pk64F may encode a protein kinase.

        Gene in D.melanogaster encoding product related (by sequence comparison) to the serine-threonine protein kinases of mammals. Isolated from Drosophila clones obtained with mammalian probes.
