Primary source: RGD:620522
See related: EnsemblRapid:ENSRNOG00000013774 AllianceGenome:RGD:620522
Gene type: protein coding
RefSeq status: VALIDATED
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Summary: Predicted to enable phospholipase binding activity and sequence-specific double-stranded DNA binding activity. Predicted to be a structural constituent of cytoskeleton and structural constituent of nuclear lamina. Involved in several processes, including cellular response to L-glutamate; cellular response to corticosterone stimulus; and response to xenobiotic stimulus. Located in nuclear lamina; nuclear matrix; and nuclear membrane. Human ortholog(s) of this gene implicated in adult-onset autosomal dominant demyelinating leukodystrophy and primary autosomal recessive microcephaly. Orthologous to human LMNB1 (lamin B1).

What's a GeneRIF?

Lamin B1 decline underlies age-related loss of adult hippocampal neurogenesis.
Title: Lamin B1 decline underlies age-related loss of adult hippocampal neurogenesis.
the current research provided direct evidence that LaminB1 was expressed in the developing cochlea and developmentally regulated in cochlear tissues, suggesting a possible role of LaminB1 in cochlear development. the result provided a theoretical basis for further study about the physiological function of LaminB1 in the peripheral auditory system.
Title: Differential Expression of LaminB1 in the Developing Rat Cochlea.
This differential expression pattern of lamin b1 in retinal neurons suggests that they may be involved in cellular differentiation and expression of cell-specific genes in individual retinal neurons.
Title: Nuclear lamins are differentially expressed in retinal neurons of the adult rat retina.
We now show that epitope masking in the nucleus is often responsible for failure to detect emerin and lamins in human, rat and pig tissues.
Title: The apparent absence of lamin B1 and emerin in many tissue nuclei is due to epitope masking.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
