Lamin fragment

Lamin fragment has a peptide sequence of Lys-Ala-Gly-Gln-Val-Val-Thr-Ile-Trp. Lamin polypeptides have an almost complete α-helical conformation with multiple α-helical domains separated by non-α-helical linkers that are highly conserved in length and amino acid sequence. Nuclear lamins are intermediate filament-type proteins that are the major building blocks of the nuclear lamina, a fibrous proteinaceous meshwork underlying the inner nuclear membrane. Lamins can also be localized in the nuclear interior, in a diffuse or spotted pattern. Lamins also play roles in DNA replication, chromatin organization, the spatial arrangement of nuclear pore complexes, nuclear growth, and anchorage of nuclear envelope proteins.
