Summaries for LMNB1 Gene

Entrez Gene Summary for LMNB1 Gene

  • The nuclear lamina consists of a two-dimensional matrix of proteins located next to the inner nuclear membrane. The lamin family of proteins make up the matrix and are highly conserved in evolution. During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are thought to be involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. This gene encodes one of the two B type proteins, B1. Alternative splicing results in transcript variants and a duplication of this gene is associated with autosomal dominant adult-onset leukodystrophy (ADLD). [provided by RefSeq, Oct 2010]

GeneCards Summary for LMNB1 Gene

LMNB1 (Lamin B1) is a Protein Coding gene. Diseases associated with LMNB1 include leukodystrophy, adult-onset, autosomal dominant and leukodystrophy. Among its related pathways are Cell Cycle, Mitotic and Cell Cycle, Mitotic. GO annotations related to this gene include structural molecule activity and phospholipase binding. An important paralog of this gene is LMNB2.

UniProtKB/Swiss-Prot for LMNB1 Gene

  • Lamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin

  • Leukodystrophy, demyelinating, autosomal dominant, adult-onset (ADLD) [MIM:169500]: A slowly progressive and fatal demyelinating leukodystrophy, presenting in the fourth or fifth decade of life. Clinically characterized by early autonomic abnormalities, pyramidal and cerebellar dysfunction, and symmetric demyelination of the CNS. It differs from multiple sclerosis and other demyelinating disorders in that neuropathology shows preservation of oligodendroglia in the presence of subtotal demyelination and lack of astrogliosis. {ECO:0000269 PubMed:16951681}. Note=The disease is caused by mutations affecting the gene represented in this entry.
