Lamin C is a type of protein that is part of the nuclear lamina, a structure located inside the cell nucleus. It plays a crucial role in maintaining the shape and stability of the nucleus, which houses the cell's genetic material. Lamin C is produced from the LMNA gene and is essential for various cellular functions, including DNA replication and cell division. This protein is classified as a type of intermediate filament, which helps provide structural support to cells. Mutations in the LMNA gene can lead to several diseases, including muscular dystrophy and progeria, highlighting the importance of Lamin C in overall cellular health and function.
