The different function of single phosphorylation sites of Drosophila melanogaster lamin Dm and lamin C.

PLoS ONE, 2012
Lamins' functions are regulated by phosphorylation at specific sites but our understanding of the role of such modifications is practically limited to the function of cdc 2 (cdk1) kinase sites in depolymerization of the nuclear lamina during mitosis.

Filament assembly of the C. elegans lamin in the absence of helix 1A

Nucleus, 2022
Lamins are the major constituent of the nuclear lamina, a protein meshwork underlying the inner nuclear membrane. Nuclear lamins are type V intermediate filaments that assemble into ~3.5 nm thick filaments.

An investigation into the role of lamin A in the progression of colorectal cancer [PDF]

, 2005
Nuclear lamins are type V intermediate filaments which form a proteinaceous meshwork, termed the nuclear lamina, which underlines the inner nuclear membrane and provides mechanical strength to the nucleus and maintains nuclear shape.

Overexpression and cytoplasmic localization of caspase-6 is associated with lamin A degradation in set of ovarian cancers

Biomarker Research, 2018
Background In most women with ovarian cancer, the diagnosis occurs after dissemination of tumor cells beyond ovaries. Several molecular perturbations occur ahead of tumor initiation including loss of lamin A/C. Our hypothesis was that the loss of nuclear

Inverse correlation between Lamin A/C and survival in ovarian cancer: implications for predicting responsiveness to taxane-based chemotherapy

Gynecologic Oncology Reports
Objective: Although paclitaxel is widely used to treat several solid cancers, the initial response rate in ovarian cancer is ∼60 %, but only ∼30 % in recurrent ovarian cancer.

Sorting nexin 6 enhances lamin a synthesis and incorporation into the nuclear envelope. [PDF]

PLoS ONE, 2014
Nuclear lamins are important structural and functional proteins in mammalian cells, but little is known about the mechanisms and cofactors that regulate their traffic into the nucleus.

Antagonistic contributions of A-type and B-type lamins to LBR localization and dynamics

Nucleus
Lamin B receptor (LBR) is an inner nuclear membrane protein that organizes peripheral heterochromatin and cooperates with lamins to tether chromatin at the nuclear periphery.

The role of LMNA in adipose: a novel mouse model of lipodystrophy based on the Dunnigan-type familial partial lipodystrophy mutation[S]

Journal of Lipid Research, 2009
We investigated the role of LMNA in adipose tissue by developing a novel mouse model of lipodystrophy. Transgenic mice were generated that express the LMNA mutation that causes familial partial lipodystrophy of the Dunnigan type (FPLD2).
