1 Structural insights into the mechanism of abscisic acid signaling by PYL proteins. Abscisic Acid secreted frizzled related protein 4 Homo sapiens
2 Upon binding to ABA, a PYL protein associates with type 2C protein phosphatases (PP2Cs) such as ABI1 and ABI2, inhibiting their activity; the molecular mechanisms by which PYLs mediate ABA signaling remain unknown, however. Abscisic Acid secreted frizzled related protein 4 Homo sapiens
3 Upon binding to ABA, a PYL protein associates with type 2C protein phosphatases (PP2Cs) such as ABI1 and ABI2, inhibiting their activity; the molecular mechanisms by which PYLs mediate ABA signaling remain unknown, however. Abscisic Acid secreted frizzled related protein 4 Homo sapiens
4 Together, our data reveal the mechanisms by which ABA regulates PYL-mediated inhibition of PP2Cs. Abscisic Acid secreted frizzled related protein 4 Homo sapiens
