Intrinsic structural disorder in cytoskeletal proteins.
Cytoskeleton, the internal scaffold of the cell, displays an exceptional combination of stability and dynamics. It is composed of three major filamentous networks, microfilaments (actin filaments), intermediate filaments (neurofilaments), and microtubules. Together, they ensure the physical and structural stability of the cell, whereby also mediating its large-scale structural rearrangements, m...
متن کاملStructural Studies on Cytoskeletal Proteins.
A number of componenets of cytoskeleton are very large proteins which are in their complete native form non amenable to the structure determination via X-ray diffraction techniques due to their non-globular shape and intrinsic flexibility which hinder the formation of suitable crystals. Dissecting such proteins into their representative building blocks-domains and subsequent structural studies ...
متن کاملIntrinsic Structural Disorder Confers Cellular Viability on Oncogenic Fusion Proteins
Chromosomal translocations, which often generate chimeric proteins by fusing segments of two distinct genes, represent the single major genetic aberration leading to cancer. We suggest that the unifying theme of these events is a high level of intrinsic structural disorder, enabling fusion proteins to evade cellular surveillance mechanisms that eliminate misfolded proteins. Predictions in 406 t...
متن کاملSnapShot: Intrinsic Structural Disorder
Many proteins (intrinsically disordered proteins, IDPs) or regions of proteins (intrinsically disordered regions, IDRs) lack a well-defined 3D structure under physiological conditions. Albeit unfolded and highly dynamic, these proteins are not denatured; rather, intrinsic structural disorder is their native, functional state.
متن کاملIntrinsic disorder in proteins: a challenge for (un)structural biology met by ion mobility-mass spectrometry.
The link between structure and function of a given protein is a principal tenet of biology. The established approach to understand the function of a protein is to 'solve' its structure and subsequently investigate interactions between the protein and its binding partners. However, structure determination via crystallography or NMR is challenging for proteins where localized regions or even thei...
