Gene Snapshot
Cell division cycle 37 (Cdc37) encodes a putative chaperone that inhibits Wnt and Hh signaling pathways. [Date last reviewed: 2018-09-13]
Pathway (FlyBase)
POSITIVE REGULATORS OF INSULIN-LIKE RECEPTOR SIGNALING PATHWAY -
Positive regulators of the Insulin-like Receptor signaling pathway enhance Insulin-like receptor (InR) activation or the activity of intracellular effectors. (Adapted from FBrf0232297, FBrf0230017 and FBrf0229989).
Protein Function (UniProtKB)
Co-chaperone that binds to numerous kinases and promotes their interaction with the Hsp90 complex, resulting in stabilization and promotion of their activity. Required for cytokinesis and chromosome segregation in mitosis and male meiosis.
(UniProt, Q24276)
Summary (Interactive Fly)

co-chaperone for Hsp83 - tests the proper substrates and establishes stable connection with the client protein to create a Cdc37-client protein binary complex - the binary complex binds to Hsp90 to form a ternary complex - facilitates client protein loading onto the Hsp90 chaperone machinery - maintains the stability of the JNK pathway< kinases - physically associates with Insulin receptor to promote neural stem cell reactivation - facilitates signaling in the Wnt and Hedgehog pathways - Aurora B interacts with and requires the Cdc37/Hsp90 complex for its stability

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.

                The activity of cdc2 is highly sensitive to Cdc37 levels, suggesting that the two genes may act in a common pathway to regulate cell cycle control.

                (Cutforth and Rubin, 1994)

                Mutants of Cdc37 display strong suppression of tor mutant embryos, embryos display 4 to 6 abdominal denticle belts.

                (Doyle and Bishop, 1993)

                Cdc37 is required for cell growth and viability.
