Lamin proteins are intended to support and strengthen cell structures, and are present in almost all cells in the body. They are formed by the LMNA gene, and are normally found inside or around the cell nucleus, where they provide strength to the nuclear membrane.
During normal cell function, the lamin proteins surround the nucleus with a mesh, regulating flow of molecules in and out. When a cell undergoes mitosis, the lamin proteins help to keep the nuclear envelope intact while it splits, to keep nuclear fluids from leaking and preventing outside contamination; after mitosis, the lamin proteins help each individual nuclear envelope reform. Animals contain lamins of A, B, and C types, each of which has a slightly different formation process and function.
