GDF-9 Proteins and Enzymes

Growth Differentiation Factor-9 (GDF-9) is an oocyte-secreted paracrine factor in the TGF-beta superfamily. It forms both non-covalent homodimers and heterodimers with BMP-15, which is coordinately expressed with GDF-9 in the oocyte. GDF-9 signals through TGF-beta RI/ALK-5 and BMPR-II, while the GDF-9:BMP-15 heterodimer is believed to signal throug...
