Function

Lamins are intermediate filament proteins that assemble into a filamentous meshwork, and which constitute the major components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane (PubMed:33033404). Lamins provide a framework for the nuclear envelope, bridging the nuclear envelope and chromatin, thereby playing an important role in nuclear assembly, chromatin organization, nuclear membrane and telomere dynamics (PubMed:33033404). The structural integrity of the lamina is strictly controlled by the cell cycle, as seen by the disintegration and formation of the nuclear envelope in prophase and telophase, respectively (PubMed:33033404).

Activity summary

Lamin B2 also referred to as 'ln43' or 'lmnB2' is a lamin molecule with a molecular weight of approximately 66 kDa. It is an important component of the nuclear lamina an essential structure that provides mechanical support to the nuclear envelope. Lamin B2 is expressed in most cell types and is particularly abundant in cells with high proliferative capacity such as those in the fetal brain and liver. The protein is encoded by the LMNB2 gene and functions as an integral part of the nuclear envelope's architecture by interacting with other nuclear proteins.

Biological function summary

Lamin B2 plays a critical role in maintaining nuclear stability and chromatin organization. It is a part of a larger complex that includes Lamin B and other nuclear matrix proteins. This structural matrix is important for chromosomal segregation during cell division ensuring that the genetic material is evenly distributed between daughter cells. Lamin B2 also facilitates processes such as DNA replication and repair by serving as a scaffold for anchoring various molecular components within the nucleus.

Pathways

Lamin B2 is implicated in the regulation of the mitotic spindle formation during cell division which is a part of the cell cycle pathway. It interacts with proteins such as Lamin A and other nucleoporins contributing to the proper formation of nuclear pore complexes. Furthermore it plays a role in the pathway of apoptosis by modulating the release of factors from the nucleus that trigger cell death mechanisms. These interactions emphasize its importance in maintaining cellular function and integrity.

Associated diseases and disorders

Alterations in Lamin B2 expression or function have been linked to certain types of cancer such as glioblastoma as well as to laminopathies. Laminopathies are a group of disorders caused by mutations in lamin proteins leading to defects in nuclear structure and function. Besides aberrant Lamin B2 is associated with neurological disorders through its interactions with other nuclear envelope protein components like Lamin A/C. These connections highlight the importance of Lamin B2 in both physiological processes and pathologies.
