Entrez Gene Summary 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 pelger-huet anomaly and reynolds syndrome. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include lamin binding and oxidoreductase activity, acting on the CH-CH group of donors, NAD or NADP as acceptor. An important paralog of this gene is TM7SF2.

Post-translational modifications for LBR Gene

  • Phosphorylated by CDK1 in mitosis when the inner nuclear membrane breaks down into vesicles that dissociate from the lamina and the chromatin. It is phosphorylated by different protein kinases in interphase when the membrane is associated with these structures. Phosphorylation of LBR and HP1 proteins may be responsible for some of the alterations in chromatin organization and nuclear structure which occur at various times during the cell cycle. Phosphorylated by SRPK1. In late anaphase LBR is dephosphorylated, probably by PP1 and/or PP2A, allowing reassociation with chromatin.
  • Ubiquitination at Lys107, Lys116, Lys123, Lys190, and Lys601

Disorders for LBR Gene

(3) OMIM Diseases for LBR Gene (600024)


  • Pelger-Huet anomaly (PHA) [MIM:169400]: An autosomal dominant inherited abnormality of granulocytes, characterized by abnormal ovoid shape, reduced nuclear segmentation and an apparently looser chromatin structure. Some individuals occasionally have skeletal anomalies, developmental delay, and seizures. {ECO:0000269 PubMed:14617022}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Greenberg dysplasia (GRBGD) [MIM:215140]: A rare autosomal recessive chondrodystrophy characterized by early in utero lethality. Affected fetuses typically present with fetal hydrops, short-limbed dwarfism, and a marked disorganization of chondro-osseous calcification, and ectopic ossification centers. {ECO:0000269 PubMed:12618959}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Reynolds syndrome (REYNS) [MIM:613471]: A syndrome specifically associating limited cutaneous systemic sclerosis and primary biliary cirrhosis. It is characterized by liver disease, telangiectasia, abrupt onset of digital paleness or cyanosis in response to cold exposure or stress (Raynaud phenomenon), and variable features of scleroderma. The liver disease is characterized by pruritis, jaundice, hepatomegaly, increased serum alkaline phosphatase and positive serum mitochondrial autoantibodies, all consistent with primary biliary cirrhosis. {ECO:0000269 PubMed:20522425}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
