FunctionGREM2_MOUSE Cytokine that inhibits the activity of BMP2 and BMP4 in a dose-dependent manner. Antagonized BMP4-induced suppression of progesterone production in granulosa cells.[1] Publication Abstract from PubMedThe bone morphogenetic proteins (BMPs) are secreted ligands largely known for their functional roles in embryogenesis and tissue development. A number of structurally diverse extracellular antagonists inhibit BMP ligands to regulate signaling. The differential screening-selected gene aberrative in neuroblastoma (DAN) family of antagonists represents the largest group of BMP inhibitors; however, little is known of how they mechanistically inhibit BMP ligands. Here, we present the structure of the DAN family member, protein related to Dan and Cerberus (PRDC), solved by X-ray crystallography. The structure reveals a growth factor-like appearance with an unexpected dimerization mechanism that is formed through extensive beta strand contacts. Using site-directed mutagenesis coupled with in vitro and in vivo activity assays, we identified a BMP-binding epitope on PRDC. We also determined that PRDC binds heparin with high affinity and that heparin binding to PRDC interferes with BMP antagonism.
