The protein encoded by this gene is a member of the TGF-β superfamily. It is a paracrine signaling molecule involved in oocyte and follicular development. Using Northern blot analysis, BMP15 has been shown to be exclusively expressed in the ovaries. It is thought that this protein may be involved in oocyte maturation and follicular development as a homodimer or by forming heterodimers with a related protein, Gdf9. The functions of BMP15 include: Defects in BMP15 are associated with primary ovarian insufficiency. BMP15may represent a biomarker of ovarian response to ovarian stimulation or oocyte quality.
