Coiled-Coil Domains of SUN Proteins as Intrinsic Dynamic Regulators.
SUN proteins are the core components of LINC complexes that span across the nuclear envelope for nuclear positioning and migration. SUN proteins contain at least one predicted coiled-coil domain preceding the SUN domain. Here, we found that the two coiled-coil domains (CC1 and CC2) of SUN2 exhibit distinct oligomeric states. CC2 is a monomer in solution. The structure of the CC2-SUN monomer rev...
متن کاملFTIR-Spectroscopy of multistranded coiled coil proteins.
Coiled coils of different order were investigated using infrared (IR) spectroscopy. Recently, we demonstrated that dimeric coiled coils display unique vibrational spectra with at least three separable bands instead of only one band of a classical alpha-helix in the amide I region. This was attributed to a distortion of the helical structure by the supercoil bending, giving rise to bands that ar...
متن کاملPredicting coiled-coil regions in proteins.
The past several years have seen significant advances in our ability to recognize coiled coils from protein sequences and model their structures. New methods include a detection program based on pairwise residue correlations, a program that distinguishes two-stranded from three-stranded coiled coils and a routine for modelling the coordinates of the core residues in coiled coils. Several widely...
متن کاملGenome-wide identification and comparative analysis of coiled-coil proteins
The α-helical coiled-coil domain is a protein structure motif with a characteristic repeat pattern well suited for computer-based prediction. Long coiled-coil proteins play an important role in organizational and regulatory processes within cells and have been implicated in a number of human diseases. Knowledge about plant or prokaryotic long coiled-coil proteins however has been limited to a f...
متن کاملCoiled-Coil Proteins Facilitated the Functional Expansion of the Centrosome
Repurposing existing proteins for new cellular functions is recognized as a main mechanism of evolutionary innovation, but its role in organelle evolution is unclear. Here, we explore the mechanisms that led to the evolution of the centrosome, an ancestral eukaryotic organelle that expanded its functional repertoire through the course of evolution. We developed a refined sequence alignment tech...
