Growth factors synthesized by ovarian somatic cells directly affect oocyte growth and function. Growth differentiation factor-9 (GDF9) is expressed in oocytes and is thought to be required for ovarian folliculogenesis. GDF9 is a member of the transforming growth factor-beta superfamily. [provided by RefSeq, Jul 2008]
Function:
Required for ovarian folliculogenesis. Promotes primordial follicle development. Stimulates granulosa cell proliferation. Promotes cell transition from G0/G1 to S and G2/M phases, through an increase of CCND1 and CCNE1 expression, and RB1 phosphorylation. It regulates STAR expression and cAMP-dependent progesterone release in granulosa and thecal cells. Attenuates the suppressive effects of activin A on STAR expression and progesterone production by increasing the expression of inhibin B. It suppresses FST and FSTL3 production in granulosa-lutein cells.
Subunit:
Homodimer or heterodimer (Potential). But, in contrast to other members of this family, cannot be disulfide-linked (By similarity).
Subcellular Location:
Secreted (By similarity).
Tissue Specificity:
Expressed in ovarian granulosa cells. Present in oocytes of primary follicles (at protein level).
Post-translational modifications:
Phosphorylated; phosphorylation is critical for GDF9 function. In vitro, can be phosphorylated by CK at Ser-325.
DISEASE:
Note=Altered GDF9 function may be involved in ovarian disorders. Rare variants in GDF9 have been found in patients with premature ovarian failure and mothers of dizygotic twins.
Similarity:
Belongs to the TGF-beta family.
