Product details:
Lamins are type V intermediate filament proteins and are grouped into constitutively expressed B-type lamins and developmentally regulated A- type lamins. Lamin-binding proteins in the nuclear lamina and the nuclear interior include several protein families and/or types of proteins in higher eu karyotes such as the inner nuclear membrane proteins, lamin B receptor, emerin, and MANI, three isoforms of lamina-associated polypeptide 1 (LAP 1), and several isoforms of LAP 2. Up to six LAP 2 isoforms derive from a single gene by alternative splicing in mammals and various isoforms have been described in Xenopus. The best characterized LAP2 isoforms are the inner nuclear membrane protein LAP 2 beta and the nucleoplasmic protein LAP 2 alpha, which are identical in their N-terminal 187-amino acid constant region but differ in their C termini. While LAP 2 beta binds to B-type lamins at the nuclear periphery and was suggested to regulate nuclear lamina growth , LAP 2 alpha specifically interacts with A-type lamins within the nuclear interior as part of a detergent/salt-resistant nucleoskeletal structure.

Lamina-associated polypeptide 2 alpha (LAP2 alpha) also known as LAP2A is part of the LAP2 protein family. It has a molecular mass of approximately 76 kDa. This protein connects with the nuclear lamina and is prominently expressed in the nucleus of most cell types. LAP2 alpha interacts with chromatin and its mechanical role involves regulating interactions between chromatin and nuclear structures.
Biological function summary
LAP2 alpha contributes to processes like nuclear stability and chromatin organization. It is involved in the formation of a complex with lamin A/C facilitating the association of this nuclear lamina protein. This interaction plays a significant role in dynamically organizing the nuclear architecture throughout the cell cycle influencing cell differentiation and proliferation.
Pathways
The interaction of LAP2 alpha with lamin A/C places it in the context of the nuclear envelope dynamics. Key pathways include the regulation of genome stability and DNA repair pathways. The interaction with lamin A/C influences how cells manage genome maintenance making LAP2 alpha important for cellular homeostasis.
LAP2 alpha shows relevance to muscular dystrophy and progeria. LAP2 alpha’s interaction with lamin A/C is important because mutations in lamin A/C are known to cause Emery-Dreifuss muscular dystrophy. Additionally LAP2 alpha's role in nuclear architecture is significant in the context of Hutchinson-Gilford progeria syndrome where abnormalities in nuclear shape are evident. In these diseases LAP2 alpha's interaction or malfunction can lead to or exacerbate pathology.
