Progesterone 195-207 bone morphogenetic protein receptor type 1B Bos taurus 78-84 12142233-13 2002 BMP-4 and GDF-5, natural ligands of BMPR-IB, strongly inhibit secretion of progesterone by ovine granulosa cells in vitro, but granulosa cells from FecB(B)/FecB(B) ewes are less responsive than those from FecB(+)/FecB(+) to the action of these peptides.
