DESCRIPTION

Also known as SPY2_BOVIN, SPRY2. Antagonist of fibroblast growth factor (FGF) pathways via inhibition of FGF-mediated phosphorylation of ERK1/2 (By similarity). Thereby acts as an antagonist of FGF-induced retinal lens fiber differentiation, may inhibit limb bud outgrowth and may negatively modulate respiratory organogenesis (By similarity). Inhibits TGFB-induced epithelial-to-mesenchymal transition in retinal lens epithelial cells (By similarity). Inhibits CBL/C-CBL-mediated EGFR ubiquitination (By similarity). Forms heterodimers with SPRY1 (By similarity). Forms a tripartite complex containing GAB1, METTL13 and SPRY2 (By similarity). Within the complex interacts with METTL13 (By similarity). Interacts with RAF1 (By similarity). Interacts (via C-terminus) with TESK1 (via C-terminus); the interaction disrupts SPRY2 interaction with GRB2, potentially via disruption of SPRY2 serine dephosphorylation (By similarity). Interacts with PPP2R1A/PP2A-A and PPP2CA/PP2A-C; the interaction with PPP2CA/PP2A-C is inhibited by interaction with TESK1, possibly by vesicular sequestration of SPRY2 (By similarity). Inhibition of the interaction with the serine/threonine-protein phosphatase 2A (PP2A) holoenzyme results in loss of PP2A-mediated dephosphorylation, resulting in the loss of SPRY2 interaction with GRB2 (By similarity). Interacts with GRB2 (By similarity). Interacts with CBL/C-CBL; the interaction inhibits CBL-mediated ubiquitination of EGFR (By similarity). Interacts (via C-terminus) with CAV1 (via C-terminus) (By similarity).
