Summaries for LMNA Gene

Entrez Gene Summary for LMNA Gene

  • The nuclear lamina consists of a two-dimensional matrix of proteins located next to the inner nuclear membrane. The lamin family of proteins make up the matrix and are highly conserved in evolution. During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are thought to be involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. Alternative splicing results in multiple transcript variants. Mutations in this gene lead to several diseases: Emery-Dreifuss muscular dystrophy, familial partial lipodystrophy, limb girdle muscular dystrophy, dilated cardiomyopathy, Charcot-Marie-Tooth disease, and Hutchinson-Gilford progeria syndrome.

GeneCards Summary for LMNA Gene

LMNA (Lamin A/C) is a Protein Coding gene. Diseases associated with LMNA include Hutchinson-Gilford Progeria Syndrome and Emery-Dreifuss Muscular Dystrophy 2, Autosomal Dominant. Among its related pathways are Neurodegenerative Diseases and Mitotic Prophase. Gene Ontology (GO) annotations related to this gene include structural molecule activity. An important paralog of this gene is LMNB2.

UniProtKB/Swiss-Prot Summary for LMNA Gene

  • Lamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin. Lamin A and C are present in equal amounts in the lamina of mammals. Plays an important role in nuclear assembly, chromatin organization, nuclear membrane and telomere dynamics. Required for normal development of peripheral nervous system and skeletal muscle and for muscle satellite cell proliferation (PubMed:10080180, PubMed:22431096, PubMed:10814726, PubMed:11799477, PubMed:18551513). 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 can accelerate smooth muscle cell senescence. It acts to disrupt mitosis and induce DNA damage in vascular smooth muscle cells (VSMCs), leading to mitotic failure, genomic instability, and premature senescence.

Interacts with TMEM201 (By similarity). Proteolytically processed isoform A interacts with NARF. Interacts with SUN1. Prelamin-A/C interacts with EMD. Interacts with MLIP. Interacts with DMPK; may regulate nuclear envelope stability. Interacts with SUV39H1; the interaction increases stability of SUV39H1. Interacts with SYNE2.

    SequenceCaution:
    • Sequence=CAA27173.1; Type=Frameshift; Evidence={ECO:0000305};
    Miscellaneous:
    • There are three types of lamins in human cells: A, B, and C.
    • 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.
    • [Isoform 6]: Disease-associated isoform. Polymorphism at codon 608 results in activation of a cryptic splice donor site within exon 11, resulting in a truncated protein product that lacks the site for endoproteolytic cleavage.

Post-translational modifications for LMNA Gene

  • Increased phosphorylation of the lamins occurs before envelope disintegration and probably plays a role in regulating lamin associations.
  • Proteolytic cleavage of the C-terminal of 18 residues of prelamin-A/C results in the production of lamin-A/C. The prelamin-A/C maturation pathway includes farnesylation of CAAX motif, ZMPSTE24/FACE1 mediated cleavage of the last three amino acids, methylation of the C-terminal cysteine and endoproteolytic removal of the last 15 C-terminal amino acids. Proteolytic cleavage requires prior farnesylation and methylation, and absence of these blocks cleavage.
  • Sumoylation is necessary for the localization to the nuclear envelope.
  • Farnesylation of prelamin-A/C facilitates nuclear envelope targeting.
  • Ubiquitination at Lys135, Lys144, Lys171, Lys181, Lys78, Lys201, Lys208, Lys108, Lys265, Lys270, Lys311, Lys470, and Lys486

Nucleus. Nucleus envelope. Nucleus lamina. Nucleus, nucleoplasm. Note=Farnesylation of prelamin-A/C facilitates nuclear envelope targeting and subsequent cleavage by ZMPSTE24/FACE1 to remove the farnesyl group produces mature lamin-A/C, which can then be inserted into the nuclear lamina. EMD is required for proper localization of non-farnesylated prelamin-A/C.

P02545-LMNA_HUMAN
Tissue specificity: In the arteries, prelamin-A/C accumulation is not observed in young healthy vessels but is prevalent in medial vascular smooth muscle cells (VSMCs) from aged individuals and in atherosclerotic lesions, where it often colocalizes with senescent and degenerate VSMCs. Prelamin-A/C expression increases with age and disease. In normal aging, the accumulation of prelamin-A/C is caused in part by the down-regulation of ZMPSTE24/FACE1 in response to oxidative stress.
