ProteomicsLamin A dimer and tetramer cross-links help explain disease mutations and polymer plasticity
Lamins are intermediate filament proteins responsible for nuclear mechanical integrity. Though linked to multiple heritable diseases, lamin structure and that of other intermediate filaments remains elusive. We employed cross-linking mass spectrometry to gain structural insights into lamin A dimer a...

TranscriptomicsDeleterious assembly of the lamin A/C mutant p.S143P causes ER stress in familial dilated cardiomyopathy
Mutation of the LMNA gene, encoding nuclear lamin A and lamin C (hereafter lamin A/C), is a common cause of familial dilated cardiomyopathy (DCM). Among Finnish DCM patients, the founder mutation c.427T>C (p.S143P) is the most frequently reported genetic variant. Here, we show that p.S143P lamin A/C...

GenomicsRedistribution of the Lamin B1 genomic binding profile affects spatial rearrangement of heterochromatic domains and gene expression during senescence
Senescence is a stress responsive form of stable cell cycle exit. Senescent cells have a distinct gene expression profile, which is often accompanied by the spatial redistribution of heterochromatin into senescence-associated heterochromatic foci (SAHFs). Studying a key component of the nuclear lami...

TranscriptomicsLamin binding profiles in the ENCODE regions
A systems understanding of nuclear organization and events is critical for determining how cells divide, differentiate and respond to stimuli and for identifying the causes of diseases. Chromatin remodeling complexes such as SWI/SNF have been implicated in a wide variety of cellular processes includ...

ProteomicsLamin A molecular compression and sliding as mechanisms behind nucleoskeleton elasticity (complementary data of PXD008337)
Lamin A is a nuclear intermediate filament protein critical for nuclear architecture and mechanics and mutated in a wide range of human diseases. Yet little is known about the molecular architecture of lamins and mechanisms of their assembly. Here we use cross-linking SILAC mass spectrometry to dete...

ProteomicsAssembly of a nuclear lamin coil 2 fragment
Nuclear structure and function are governed by lamins, which are intermediate filaments mostly consisting of α-helices. Different lamin assembly models have been proposed based on low resolution or fragmented structures. However, their assembly mechanisms at the molecular level are poorly understood...

GenomicsCorrelated alterations in genome organization, histone methylation, and DNA-lamina interactions in Hutchinson-Gilford progeria syndrome (ChIP-seq)
Hutchinson-Gilford progeria syndrome (HGPS) is a premature aging disease that is frequently caused by a de novo point mutation at position 1824 in LMNA. This mutation activates a cryptic splice donor site in exon 11, and leads to an in-frame deletion within the prelamin A mRNA and the production of ...
