FHA domains are phosphoThr recognition modules found in diverse signaling proteins, including kinase-associated protein phosphatase (KAPP) from Arabidopsis thaliana. The kinase-interacting FHA domain (KI-FHA) of KAPP targets it to function as a negative regulator of some receptor-like kinase (RLK) signaling pathways important in plant development and(More)
Gram-negative phytopathogenic bacteria, such as Pseudomonas syringae, deliver multiple effector proteins into plant cells during infection. It is hypothesized that certain plant and mammalian effector proteins need to traverse the type III secretion system unfolded and are delivered into host cells as inactive enzymes. We have previously identified(More)
Forkhead-associated (FHA) domains are phosphoprotein-binding modules found in diverse signaling proteins that bind partners phosphorylated on threonine or serine. Kinase-associated protein phosphatase from Arabidopsis employs its FHA domain for negative regulation of receptor-like kinase signaling pathways, which are important in plant development. The(More)
A net increase in the backbone rigidity of the kinase-interacting FHA domain (KI-FHA) from the Arabidopsis receptor kinase-associated protein phosphatase (KAPP) accompanies the binding of a phosphoThr peptide from its CLV1 receptor-like kinase partner, according to (15)N NMR relaxation at 11.7 and 14.1 T. All of the loops of free KI-FHA display evidence of(More)
Amblyopia is a neurodevelopmental disorder of vision that occurs when the visual cortex receives decorrelated inputs from the two eyes during an early critical period of development. Amblyopic eyes are subject to suppression from the fellow eye, generate weaker visual evoked potentials (VEPs) than fellow eyes and have multiple visual deficits including(More)
The first potentiometric transducer for G-quadruplex/hemin DNAzyme-based biosensing has been developed by using potential responses of electrically neutral oligomeric phenols on polymeric membrane electrodes. In the presence of G-quadruplex/hemin DNAzyme and H(2)O(2), monomeric phenols (e.g., phenol, methylphenols, and methoxyphenols) can be condensed into(More)
PURPOSE There is growing evidence that abnormal binocular interactions play a key role in the amblyopia syndrome and represent a viable target for treatment interventions. In this context the use of partial occlusion using optical devices such as Bangerter filters as an alternative to complete occlusion is of particular interest. The aims of this study were(More)
