Gene Information

human ... LMNA(4000)

General description

Lamin-A is a key component of the nuclear lamina, a protein network underlying the inner membrane that determines nuclear shape and size. The same gene (Lmna, Dhe, or Lamn1 in murine species; Gene ID 16905) that encodes lamin-A also codes for the alternatively spliced prelamin-C isoforms (UniProt P48678-2 and P48678-3). Murine lamin-A (UniProt P48678-1) is initially produced as a 665-amino acid prelamin A, which is further processed posttranslationally by four enzymatic steps to yield the mature Lamin-A. Farnesylation of Cys662, endoproteolytic cleavage of the last three amino acids (a.a. 663-665), carboxyl methylation of Cys662, and the final endoproteolytic removal of the remaining propeptide sequence (a.a. 648-662), including the farnesylated Cys662, catalyzed by the ER membrane zinc metalloproteinase ZMPSTE24.

Hutchinson-Gilford progeria syndrome (HGPS or progeria) is typically caused by a dominant-negative C•G-to-T•A mutation (c.1824 C>T; p.G608G) in LMNA, the gene that encodes nuclear lamin A. This mutation causes RNA mis-splicing that produces progerin, a toxic protein that induces rapid

The global coronavirus disease 2019 (COVID-19) pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a positive-sense RNA virus. How the host immune system senses and responds to SARS-CoV-2 infection remain largely unresolved. Here, we report that SARS-CoV-2
