CC -!- FUNCTION: Antagonist of fibroblast growth factor (FGF) pathways via
CC inhibition of FGF-mediated phosphorylation of ERK1/2 (By similarity).
CC Thereby acts as an antagonist of FGF-induced retinal lens fiber
CC differentiation, may inhibit limb bud outgrowth and may negatively
CC modulate respiratory organogenesis (By similarity). Inhibits TGFB-
CC induced epithelial-to-mesenchymal transition in retinal lens epithelial
CC cells (By similarity). Inhibits CBL/C-CBL-mediated EGFR ubiquitination
CC (By similarity). {ECO:0000250|UniProtKB:O43597,
CC ECO:0000250|UniProtKB:Q9QXV8}.
CC -!- SUBUNIT: Forms heterodimers with SPRY1 (By similarity). Forms a
CC tripartite complex containing GAB1, METTL13 and SPRY2 (By similarity).
CC Within the complex interacts with METTL13 (By similarity). Interacts
CC with RAF1 (By similarity). Interacts (via C-terminus) with TESK1 (via
CC C-terminus); the interaction disrupts SPRY2 interaction with GRB2,
CC potentially via disruption of SPRY2 serine dephosphorylation (By
CC similarity). Interacts with PPP2R1A/PP2A-A and PPP2CA/PP2A-C; the
CC interaction with PPP2CA/PP2A-C is inhibited by interaction with TESK1,
CC possibly by vesicular sequestration of SPRY2 (By similarity).
CC Inhibition of the interaction with the serine/threonine-protein
CC phosphatase 2A (PP2A) holoenzyme results in loss of PP2A-mediated
CC dephosphorylation, resulting in the loss of SPRY2 interaction with GRB2
CC (By similarity). Interacts with GRB2 (By similarity). Interacts with
CC CBL/C-CBL; the interaction inhibits CBL-mediated ubiquitination of EGFR
CC (By similarity). Interacts (via C-terminus) with CAV1 (via C-terminus)
CC (By similarity). {ECO:0000250|UniProtKB:O43597,
CC ECO:0000250|UniProtKB:Q9QXV8}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:O43597}. Cell projection, ruffle membrane
CC {ECO:0000250|UniProtKB:O43597}. Note=Associated with microtubules in
CC unstimulated cells but is translocated to the membrane ruffles in cells
CC stimulated ith EGF (epidermal growth factor).
CC {ECO:0000250|UniProtKB:O43597}.
CC -!- DOMAIN: The Cys-rich domain is responsible for the localization of the
CC protein to the membrane ruffles. {ECO:0000250}.
CC -!- PTM: Cleaved at Pro-144 by the prolyl endopeptidase FAP (seprase)
CC activity (in vitro). {ECO:0000250|UniProtKB:O43597}.
CC -!- SIMILARITY: Belongs to the sprouty family. {ECO:0000305}.
