Description
Product Characteristics:
Lamins are nuclear membrane proteins that serve to maintain specific cellular functions, such as DNA replication and chromatin organization. Lamin B receptor (LBR) is an integral protein of the nuclear envelope inner membrane. It is phosphorylated by CDC2 protein kinase 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. The cleavage of lamins results in nuclear disregulation and cell death.
Subcellular location: Cytoplasm, Nucleus, Cell membrane
Synonyms: PHA, LMN2R, TDRD18, DHCR14B, Lamin-B receptor, Integral nuclear envelope inner membrane protein, LBR
Target Information: 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]
