2024年12月25日 · LMNB1 (Lamin B1) is a Protein Coding gene. Diseases associated with LMNB1 include Leukodystrophy, Demyelinating, Adult-Onset, Autosomal Dominant and Microcephaly 26, Primary, Autosomal Dominant. Among its related pathways are Apoptosis and survival FAS signaling cascades and Defective Intrinsic Pathway for Apoptosis.

There are 2 types of vertebrate lamins, including A and B. The 2 B type proteins are encoded by lamin B1 (LMNB1) and lamin B2 (LMNB2). The LMNBs factor has been found to be associated with the development of multiple tumors, but its association with …

2025年2月9日 · This gene encodes one of the two B-type lamin proteins and is a component of the nuclear lamina. A duplication of this gene is associated with autosomal dominant adult-onset leukodystrophy (ADLD). Alternative splicing results in multiple transcript variants.

2016年1月7日 · LMNB1 -related autosomal dominant leukodystrophy (ADLD) is a slowly progressive disorder of central nervous system white matter characterized by onset of autonomic dysfunction in the fourth to fifth decade, followed by pyramidal and cerebellar abnormalities resulting in spasticity, ataxia, and tremor.

LMNB1 encodes a deduced 586-amino acid protein with a calculated molecular mass of 66,334 Da. The LMNB1 protein shares approximately 72% sequence similarity with lamin A/C (150330). Lamin B, a component of the interphase nuclear lamina, is required to maintain nuclear shape and mechanical integrity (Goldman et al., 2002).

2021年3月29日 · Lamin B2 (LMNB2) is involved in chromatin remodeling and the rupture and reorganization of nuclear membrane during mitosis, which is necessary for eukaryotic cell proliferation. However, the...

Objective: Duplication of the LMNB1 gene encoding lamin B1 causes adult-onset autosomal-dominant leukodystrophy (ADLD) starting with autonomic symptoms, which are followed by pyramidal signs and ataxia. Magnetic resonance imaging (MRI) of the brain reveals characteristic findings. This is the first longitudinal study on this disease.

Lamin B1 is a scaffolding (supporting) component of the nuclear envelope, which is the structure that surrounds the nucleus in cells. Specifically, this protein is located in the nuclear lamina, a mesh-like layer of intermediate filaments and other proteins that is attached to the inner membrane of the nuclear envelope.

2021年5月21日 · Our study confirmed that LMNB1 and DLGAP5 were up-regulated in gliomas, and patients with high expression of LMNB1 or DLGAP5 had poor survival rate. Furthermore, silence of LMNB1 and DLGAP5 inhibited the proliferation of glioma cells. Together, LMNB1 and DLGAP5 were two potentially novel molecular biomarkers for diagnosis and prognosis of glioma.
