SPRY4
Protein sprouty homolog 4 is a protein that in humans is encoded by the SPRY4 gene. Function SPRY4 is an inhibitor of the receptor-transduced mitogen-activated protein kinase (MAPK) signaling pathway. It is positioned upstream of RAS (see HRAS; MIM 190020) activation and impairs the formation of active GTP-RAS (Leeksma et al., 2002). Interactions SPRY4 has been shown to interact with TESK1.
