Previous GeneCards Identifiers for LBR Gene
The protein encoded by this gene belongs to the ERG4/ERG24 family. It localized in the nuclear envelope inner membrane and anchors the lamina and the heterochromatin to the membrane. It may mediate interaction between chromatin and lamin B. Mutations of this gene has been associated with autosomal recessive HEM/Greenberg skeletal dysplasia. Alternative splicing occurs at this locus and two transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]
GeneCards Summary for LBR Gene
LBR (Lamin B Receptor) is a Protein Coding gene. Diseases associated with LBR include Greenberg Dysplasia and Pelger-Huet Anomaly. Among its related pathways are Metabolism and cholesterol biosynthesis III (via desmosterol). Gene Ontology (GO) annotations related to this gene include oxidoreductase activity, acting on the CH-CH group of donors, NAD or NADP as acceptor. An important paralog of this gene is TM7SF2.
UniProtKB/Swiss-Prot Summary for LBR Gene
Catalyzes the reduction of the C14-unsaturated bond of lanosterol, as part of the metabolic pathway leading to cholesterol biosynthesis (PubMed:9630650, PubMed:12618959, PubMed:16784888, PubMed:21327084, PubMed:27336722). Plays a critical role in myeloid cell cholesterol biosynthesis which is essential to both myeloid cell growth and functional maturation (By similarity). Mediates the activation of NADPH oxidases, perhaps by maintaining critical levels of cholesterol required for membrane lipid raft formation during neutrophil differentiation (By similarity). Anchors the lamina and the heterochromatin to the inner nuclear membrane (PubMed:10828963).
