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:28716252, PubMed:32910914). 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:28716252, PubMed:32910914). 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:28716252, PubMed:32910914).

Lamin B1 also known as LMNB1 is a protein that plays an important role in the structure of the nuclear lamina a dense fibrillar network inside the nucleus of cells. This protein belongs to the lamin family and has an approximate molecular weight of 66 kDa. Lamin B1 is expressed in nearly all types of cells acting as a structural component by interacting with chromatin and anchoring the nuclear envelope. It contributes to regulating nuclear stability and mechanical support which is essential for proper cell function.
Lamin B1 serves many important functions by providing structural integrity and regulating gene expression through chromatin organization. Part of the nuclear lamina complex Lamin B1 interacts with other lamin proteins such as Lamin A and Lamin C forming a mesh-like structure that supports the nuclear envelope. This protein also affects cellular processes such as DNA replication RNA transcription and cell division indicating its broad impact on various cellular activities.
Lamin B1 plays an important role in gene expression regulation and cell cycle control. It interacts with pathways involved in chromatin remodeling influencing the access of transcription factors to DNA which affects gene expression profiles. Lamin B1 associates with related proteins such as Lamin A/C and other nuclear matrix proteins to maintain cellular architecture stability and normal cell function. This organization is vital to ensure the accuracy of cellular processes and prevent anomalies during cell division.
Mutations or altered expression of Lamin B1 have been associated with several pathological conditions. One noteworthy disorder is autosomal dominant adult-onset leukodystrophy where Lamin B1 expression levels are abnormal. This protein also connects to multiple sclerosis through its role in maintaining nuclear architecture. Additionally changes in Lamin B1 expression levels can influence pathways involving Lamin A/C and potentially lead to other laminopathies highlighting its influence in maintaining cellular health and contributing to disease development.
