1 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 abl interactor 1 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 abl interactor 1 Homo sapiens
3 Here we report three crystal structures: apo-PYL2, (+)-ABA-bound PYL2 and (+)-ABA-bound PYL1 in complex with phosphatase ABI1. Abscisic Acid abl interactor 1 Homo sapiens
4 Here we report three crystal structures: apo-PYL2, (+)-ABA-bound PYL2 and (+)-ABA-bound PYL1 in complex with phosphatase ABI1. Abscisic Acid abl interactor 1 Homo sapiens
5 In response to ABA binding, loop CL2 closes onto the pocket, creating a surface that recognizes ABI1. Abscisic Acid abl interactor 1 Homo sapiens
