DESCRIPTION

Also known as SPY4_HUMAN, SPRY4. Suppresses the insulin receptor and EGFR-transduced MAPK signaling pathway, but does not inhibit MAPK activation by a constitutively active mutant Ras (PubMed:12027893). Probably impairs the formation of GTP-Ras (PubMed:12027893). Inhibits Ras-independent, but not Ras-dependent, activation of RAF1 (PubMed:12717443). Represses integrin-mediated cell spreading via inhibition of TESK1-mediated phosphorylation of cofilin (PubMed:15584898). Interacts (via C-terminus) with TESK1 (via both C- and N-termini); the interaction inhibits TESK1 kinase activity (PubMed:12027893, PubMed:15584898). Interacts with RAF1 (PubMed:12717443). Interacts with CAV1 (via C-terminus) (By similarity).
