  • 功能：
    Required for left-right (L-R) asymmetry determination of organ systems in mammals. May play a role in endometrial bleeding.

    2. LeftyA leads to disruption of Rac1 and Pak1 activity with subsequent actin depolymerization, cell softening and cell shrinkage. PMID: 27404958
    3. LEFTY2 down-regulates MKi67 expression and FAK activity, up-regulates miR-200a and E-cadherin, and is thus a powerful negative regulator of endometrial cell proliferation and migration. PMID: 27497669

    5. Lefty A may account for the tumor suppressive activity of human adult stem cells. PMID: 22469982
    6. Findings suggest that Lefty2 is negatively modulated by miR-302s in hESCs, which plays an important role in maintaining the balance between pluripotency and germ layer specification. PMID: 21266536
    7. Findings show that during embryonic development, EBAF/LEFTY B plays important roles in decidualization and embryo implantation. PMID: 21401636
