Gene Information
human ... lamin B1(4001)
General description
LMNB1 (lamin B1) is a B type lamin protein. LMNB1 is abundantly expressed in various cell types. This gene is located on human chromosome 5q23. The nuclear lamina, an intermediate filament meshwork, is made of LmnB1, LmnB2, A type (LmnA/C) and associated inner nuclear membrane proteins.
This product was derived from ATCC Cat. No. HTB-96.
U2OS GFP-LMNB1 are osteosarcoma, epithelial cells, from a human caucasian female (aged 15 years), with a GFP-tagged modification.
Application
This product is a human U2OS cell line in which the genomic LaminB1 gene has been endogenously tagged with a Green Fluorescent Protein (GFP) gene using CompoZr® Zinc Finger Nuclease technology. Integration resulted in endogenous expression of the fusion protein in which GFP is attached to the N-terminus of LaminB1. Fluorescence imaging shows the characteristic LaminB1 nuclear expression. This stable cell line was expanded from a single clone. The target′s gene regulation and corresponding protein function are preserved in contrast to cell lines with overexpression via an exogenous promoter.

Biochem/physiol Actions
Lamin B1 (LMNB1) is essential for proper chromosome condensation in interphase nuclei. It also participates in the distribution of heterochromatin and modulation of gene expression and splicing. Mutations in LMNB1 (lamin B1) gene results in the adult onset demyelinating disease autosomal dominant leukodystrophy (ADLD).
Nuclear lamin B1 encoded by LMNB1 gene is an intermediate filament protein of the nuclear envelope. The protein has transcriptional co-regulatory activity. It plays a key role in DNA replication, cellular aging and stress responses. Overexpression of the gene has been observed in hepatocellular carcinoma (HCC) patients. Thus, LMNB1 can be used as a potential biomarker for HCC.
