Lamin a c is a type v nuclear lamin.

What is lamin a c.

Nuclear lamins a b1 b2 and c. Haplo insufficiency in the cardiomyocyte nuclei. During apoptosis lamin a c is specifically cleaved into a large 41 50 kda and a small 28 kda fragment 3 4. Biogenesis of lamin a in normal cells and the failure to generate mature lamin a in hutchinson gilford progeria.

Lamin a c belongs to the lamin family of proteins. The lamin a protein must be processed within the cell before becoming part of the lamina. Lamin c does not have to undergo this processing before becoming part of the lamina. Two isoforms lamins a and c can be created from this gene via alternative splicing.

Lamin a was detected in 10 to 20 of hgps lymphocytes. Lamins a and c are identical for the first 566 amino acids with lamin c differing only in six unique carboxy terminal amino acids. 290 the transcript from the gene is spliced differentially to give rise to the two different forms lamin a and lamin c. 17 37 this is due to either the degradation of the mutated mrna carrying a premature stop codon via the non sense mediated decay pathway or to the degradation of the corresponding truncated lamin.

Not intended for diagnostic or therapeutic use. Lamin a c expression explored in various explanted heart tissues from patients carrying nonsense lmna mutations revealed reduced lamin a c level i e. The cleavage of lamins results in nuclear dysregulation and cell death 5 6. During apoptosis lamin a c is specifically cleaved into a large 41 50 kda and a small 28 kda fragment 3 4.

Lamin a c is an intermediate filament lining the inner nuclear membrane part of the nuclear envelope. For research use only. Western blot analysis showed 25 of normal lamin a levels and no truncated form was detected. Prelamin a and lamin c differ in structure only at the carboxyl terminus.

Lamin a c is cleaved by caspase 6 and serves as a marker for caspase 6 activation. Lmna also known as lamin a c is a protein that in humans is encoded by the lmna gene. The lamins are components of the nuclear lamina a fibrous layer on the nucleoplasmic side of the inner nuclear membrane which is suggested to provide a framework for the nuclear envelope and may interact with chromatin. Lamin a c is cleaved by caspase 6 and serves as a marker for caspase 6 activation.

Unlike lamin c lamin a is generated in a precursor form called prelamin a. The cleavage of lamins results in nuclear dysregulation and cell death 5 6. Lamin c is a splice variant of lamin a differing only at the carboxy terminus.
