Secreted Frizzled-related proteins in animal development
摘要
Secreted Frizzled-related proteins (SFRPs) are a small, ancient family of extracellular signaling pathway agonists and antagonists. As part of the intercellular communication system, they regulate signaling pathways significant for animal development including Wnt and BMP. This review summarizes the current knowledge of SFRP functions, focusing on recent discoveries that offer new insights into the role of interactions between SFRPs and Wnt signaling pathways in morphogenesis.
