– Directly antagonizes activity of BMP2, BMP4, BMP6 and BMP7 in a dose-dependent manner. May be involved in the onset of endometrial receptivity for implantation/sensitization for the decidual cell reaction. Enhances Wnt signaling and inhibits TGF-beta signaling. SOSTDC1 Protein, Rat, Recombinant (His & Myc) is expressed in HEK293 mammalian cells with N-10xHis and C-Myc tag. The predicted molecular weight is 24.6 kDa and the accession number is Q642G2.
