The function of ENSG00000198369 (SPRED2, sprouty related EVH1 domain containing 2) is as follows. Negatively regulates Ras signaling pathways and downstream activation of MAP kinases (PubMed:15683364, PubMed:34626534). Recruits and translocates NF1 to the cell membrane, thereby enabling NF1- dependent hydrolysis of active GTP-bound Ras to inactive GDP-bound Ras (PubMed:34626534). Inhibits fibroblast growth factor (FGF)-induced retinal lens fiber differentiation, probably by inhibiting FGF-mediated phosphorylation of ERK1/2 (By similarity). Inhibits TGFB-induced epithelial-to-mesenchymal transition in lens epithelial cells (By similarity). {ECO:0000250|UniProtKB:Q924S7, ECO:0000269|PubMed:15683364, ECO:0000269|PubMed:34626534}.
