Function
Lamin-A/C. Lamins are intermediate filament proteins that assemble into a filamentous meshwork, and which constitute the major components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane (PubMed:10080180, PubMed:10580070, PubMed:10587585, PubMed:10814726, PubMed:11799477, PubMed:12075506, PubMed:12927431, PubMed:15317753, PubMed:18551513, PubMed:18611980, PubMed:2188730, PubMed:22431096, PubMed:2344612, PubMed:23666920, PubMed:24741066, PubMed:31434876, PubMed:31548606, PubMed:37788673, PubMed:37832547). Lamins provide a framework for the nuclear envelope, bridging the nuclear envelope and chromatin, thereby playing an important role in nuclear assembly, chromatin organization, nuclear membrane and telomere dynamics (PubMed:10080180, PubMed:10580070, PubMed:10587585, PubMed:10814726, PubMed:11799477, PubMed:12075506, PubMed:12927431, PubMed:15317753, PubMed:18551513, PubMed:18611980, PubMed:22431096, PubMed:23666920, PubMed:24741066, PubMed:31548606, PubMed:37788673, PubMed:37832547). Lamin A and C also regulate matrix stiffness by conferring nuclear mechanical properties (PubMed:23990565, PubMed:25127216). The structural integrity of the lamina is strictly controlled by the cell cycle, as seen by the disintegration and formation of the nuclear envelope in prophase and telophase, respectively (PubMed:2188730, PubMed:2344612). Lamin A and C are present in equal amounts in the lamina of mammals (PubMed:10080180, PubMed:10580070, PubMed:10587585, PubMed:10814726, PubMed:11799477, PubMed:12075506, PubMed:12927431, PubMed:15317753, PubMed:18551513, PubMed:18611980, PubMed:22431096, PubMed:23666920, PubMed:31548606). Also invoved in DNA repair: recruited by DNA repair proteins XRCC4 and IFFO1 to the DNA double-strand breaks (DSBs) to prevent chromosome translocation by immobilizing broken DNA ends (PubMed:31548606). Required for normal development of peripheral nervous system and skeletal muscle and for muscle satellite cell proliferation (PubMed:10080180, PubMed:10814726, PubMed:11799477, PubMed:18551513, PubMed:22431096). Required for osteoblastogenesis and bone formation (PubMed:12075506, PubMed:15317753, PubMed:18611980). Also prevents fat infiltration of muscle and bone marrow, helping to maintain the volume and strength of skeletal muscle and bone (PubMed:10587585). Required for cardiac homeostasis (PubMed:10580070, PubMed:12927431, PubMed:18611980, PubMed:23666920). Prelamin-A/C. Prelamin-A/C can accelerate smooth muscle cell senescence (PubMed:20458013). It acts to disrupt mitosis and induce DNA damage in vascular smooth muscle cells (VSMCs), leading to mitotic failure, genomic instability, and premature senescence (PubMed:20458013).

Supplementary info
- This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
Lamin A also known as LMNA is a type of lamin protein integral to the nuclear architecture. It has a molecular weight of approximately 70 kDa. This protein localizes mainly to the nuclear lamina a dense fibrillar network inside the inner nuclear membrane found across various cell types. Lamin A serves as a structural scaffold mediating nuclear stability and rigidity. It also plays a role in chromatin organization supporting overall nuclear functions.
- Biological function summary
The lamin molecule interacts with several nuclear components forming part of the nuclear lamina complex. It anchors chromatin material and regulates DNA replication and repair. Lamin A protein also modulates gene expression through interactions with transcription factors. Beyond structural support it influences cell cycle progression and differentiation impacting cellular mechanotransduction and signaling processes.
- Pathways
Lamin A performs critical functions within the cell cycle and apoptotic pathways. Its interactions with the retinoblastoma protein (pRB) and other cyclin-dependent kinases control cell cycle checkpoints and progression. Moreover lamin A connects with proteins involved in signaling pathways like MAPK which relate to stress responses and cellular growth. These interactions highlight its dynamic involvement in maintaining cell health and proliferation.
- Associated diseases and disorders
Mutations in the lamin A gene associate closely with Hutchinson-Gilford Progeria Syndrome and Emery-Dreifuss Muscular Dystrophy. In these conditions altered lamin A protein affects nuclear shape and chromatin layout disrupting transcriptional regulation. The mutated lamin A protein interacts differently with binding partners like emerin contributing to muscle adipose tissue and multi-system abnormalities. This highlights the critical role lamin A plays in maintaining normal cellular function across life stages.
