    text
  • lamellipodium
  • found in the cytoplasm in unstimulated cells
  • translocated to the membrane ruffles in cells stimulated with EGF
  • basic FUNCTION
  • palmitoylated phosphoprotein that can attenuate or potentiate numerous growth factor-induced signaling pathways
  • may function as an antagonist of fibroblast growth factor (FGF) pathways
  • may negatively modulate respiratory organogenesis
  • induced by TCR signal, and negatively regulates further TCR signaling by interacting with proximal signaling molecules in immune synapse
  • inhibits angiogenesis in association with up-regulation of CDKN1A, CDKN1B
  • critical regulator of adipocyte differentiation and mesenchymal stem cell (MSC) lineage allocation, potentially acting through regulation of CEBPB and TAZ
  • is potentially an important regulator of craniofacial and cardiac morphogenesis and perturbations in SPRY1 levels may contribute to congenital disorders involving tissues of neural crest origin
  • endogenous angiogenesis inhibitor
  • playing a role in the regulation of signal transduction
  • negatively regulates primitive hematopoiesis and endothelial cell function
  • SPRY1, SPRY2, SPRY3, SPRY4, are central and complex regulators of the receptor tyrosine kinase (RTK) signalling pathway
  • cytoplasmic localized cellular target for E1A oncoproteins to regulate the RTK signalling pathway, and consequently cellular events downstream of RTK that are essential for viral replication and transformation
  • 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
  • is a candidate tumor-suppressor gene in medullary thyroid carcinoma

    protein
  • 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)
  • with Sprouty2 bind to the adaptor protein CRKL in a stimulus-dependent manner
  • SPRY1 and SPRY2, associate with the HECT domain family E3 ubiquitin ligase, NEDD4
  • FGF13 regulates proliferation and differentiation of skeletal muscle by down-regulating SPRY1
