  • C terminal cysteine-rich domain, responsible for the localization of the protein to the membrane ruffles
  • conjugated PhosphoP
  • sprouty family
  • CATEGORY tumor suppressor , signaling growth factor
    SUBCELLULAR LOCALIZATION     intracellular
    text associated with microtubules in unstimulated cells but translocated to the membrane ruffles in cells stimulated by EGF (epidermal growth factor)
    basic FUNCTION
  • palmitoylated phosphoprotein that can attenuate or potentiate numerous growth factor-induced signaling pathways
  • required for growth factor stimulated translocation of the protein to membrane ruffles
  • may be playing a role in alveoli branching during lung development
  • key antagonistic regulator of RTK signalling and suppression of its expression or function may facilitate proliferation and angiogenesis
  • acting as a potential tumour suppressor locus in prostate carcinoma
  • inhibiting growth and migration of vascular smooth muscle cell, and may be decreasing neointimal growth after blood vessel injury
  • playing a role during the final stages of follicle maturation and corpus luteum formation
  • involved in the control of neuritic growth
  • involved in the development of the CNS by inhibiting both neuronal differentiation and survival through a negative-feedback loop that downregulates neurotrophic factors-driven signaling pathways
  • playing a necessary role for tumor formation by H-Ras-transformed fibroblasts
  • both redundant and non-redundant functions for SPRY2 and SPRY4 on embryonic development and FGF signaling
  • playing a crucial, permissive role in the anti-apoptotic actions of serum
  • involved in male sex organogenesis by controlling fibroblast growth factor 9-induced mesonephric cell migration to the developing testis
  • inhibits apoptosis in response to DNA damage by regulating AKT1, MDM2, and TP53, by a process mediated partly by RAC1
  • acts as an inhibitor of CRKL-RAP1 signaling
  • regulates receptor tyrosine kinase signalling and therefore cell growth and differentiation
  • induces the epithelial-to-mesenchymal transition gene ZEB1
  • potentially regulates palate mesenchymal cell proliferation via FGF signaling and is involved in palatal shelf elevation
  • SPRY1, SPRY2, SPRY3, SPRY4, are central and complex regulators of the receptor tyrosine kinase (RTK) signalling pathway
  • SPRY1, SPRY2, are targets of FGF signaling in the lens during initiation of fiber differentiation and function redundantly in the corneal epithelial cells to suppress proliferation
    a component
    small molecule
  • with FGF8 (inhibition)
  • interacting with PTEN to inhibit AKT1 activation by epidermal growth factor as well as cell proliferation
  • negative regulators of receptor tyrosine kinase (RTK) signaling
  • interacting with CAV1 (C terminus of CAV1 is the major Sprouty-binding site, whereas Sprouty binds CAV1 via its conserved C-terminal domain, and interaction modulates signaling in a growth factor- and Sprouty isoform-specific manner)
  • specific relationship between FGF6 and SPRY 2, both being known for their particular involvement in myogenesis
  • interacts with DYRK1A that regulates the phosphorylation status of SPRY2
  • SPRY1 and SPRY2, associate with the HECT domain family E3 ubiquitin ligase, NEDD4 (NEDD4 ubiquitinates SPRY2)
  • with Sprouty1 bind to the adaptor protein CRKL in a stimulus-dependent manner
  • cell & other
