Structural and functional analysis of phosphothreonine-dependent FHA domain interactions.
FHA domains are well established as phospho-dependent binding modules mediating signal transduction in Ser/Thr kinase signaling networks in both eukaryotic and prokaryotic species. Although they are unique in binding exclusively to phosphothreonine, the basis for this discrimination over phosphoserine has remained elusive. Here, we attempt to dissect overall binding specificity at the molecular...
متن کاملThe FHA domain mediates phosphoprotein interactions.
The forkhead-associated (FHA) domain is a phosphopeptide-binding domain first identified in a group of forkhead transcription factors but is present in a wide variety of proteins from both prokaryotes and eukaryotes. In yeast and human, many proteins containing an FHA domain are found in the nucleus and involved in DNA repair, cell cycle arrest, or pre-mRNA processing. In plants, the FHA domain...
متن کاملStructural delineation of MDC1-FHA domain binding with CHK2-pThr68.
Mammalian MDC1 interacts with CHK2 in the regulation of DNA damage-induced S-phase checkpoint and apoptosis, which is directed by the association of MDC1-FHA and CHK2-pThr68. However, different ligand specificities of MDC1-FHA have been reported, and no structure is available. Here we report the crystal structures of MDC1-FHA and its complex with a CHK2 peptide containing pThr68. Unlike other F...
متن کاملActivity-dependent structural and functional plasticity of astrocyte-neuron interactions.
Observations from different brain areas have established that the adult nervous system can undergo significant experience-related structural changes throughout life. Less familiar is the notion that morphological plasticity affects not only neurons but glial cells as well. Yet there is abundant evidence showing that astrocytes, the most numerous cells in the mammalian brain, are highly mobile. ...
متن کاملFha Interaction with Phosphothreonine of TssL Activates Type VI Secretion in Agrobacterium tumefaciens
The type VI secretion system (T6SS) is a widespread protein secretion system found in many Gram-negative bacteria. T6SSs are highly regulated by various regulatory systems at multiple levels, including post-translational regulation via threonine (Thr) phosphorylation. The Ser/Thr protein kinase PpkA is responsible for this Thr phosphorylation regulation, and the forkhead-associated (FHA) domain...
