SPRY2 (sprouty homolog 2) is a 35kD member of the sprouty family of proteins. It is widely expressed in embryonic and adult tissues, including endothelium. SPRY2 is considered a negative regulator of Ras/ERK signaling. For example, it appears to form a trimeric complex with PKC-delta and PKD1, blocking ERK phosphorylation. It also interacts with a number of other molecules, including CBL and SIAH2, which likely limit its availability. Human SPRY2 is 315 aa in length and contains one CBL-TKB binding site (aa53-59) that is phosphorylated at Tyr55, a Ser-rich region (aa125-131), a Cys-rich domain (aa178-301) and a PxxPxR motif that mediates ERK inhibitory activity.
