FAMILY
  • FAM10 family
  • CATEGORY tumor suppressor
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm
    basic FUNCTION
  • characterized by its ability to bind the two chaperones, HSP70 and HSP90
  • provides a physical link between HSP70 and HSP90 and modulates the activities of both of these chaperone proteins
  • displays broad anti-aggregation functions and has a critical function in preventing protein misfolding pathologies
  • functional role, in preventing the co-aggregation of HSP70 with SNCA, thereby reducing the toxicity of amyloidogenesis
  • substrate of GRK5 in cells, and phosphorylation of ST13 by GRK5 plays a role in modulating CXCR4 internalization
