LBR - lamin B receptor Gene

Also Known as PHA; C14SR; LMN2R; PHASK; TDRD18; DHCR14B

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 3930

About LBR

Cytogenetic location: 1q42.12 Genomic coordinates (GRCh38): 1:225,401,502-225,428,821 (from NCBI)

This gene has 9 transcripts (splice variants), 196 orthologues, 2 paralogues and is associated with 8 phenotypes. Ubiquitous expression in lymph node (RPKM 40.2), bone marrow (RPKM 33.5) and 23 other tissues.

Summary

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]
