| UniProt functional annotation for P20700 | |||
| UniProt code: P20700. |
| Organism: | Homo sapiens (Human). | |
| Taxonomy: | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo. | |
| Function: | Lamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin. | |
| Subunit: | Homodimer. Interacts with lamin-associated polypeptides IA, IB and 2. Interacts with SPAG4 and SEPT12. {ECO:0000269|PubMed:22265972, ECO:0000269|PubMed:25775403}. | |
| Subcellular location: | Nucleus inner membrane; Lipid-anchor; Nucleoplasmic side. | |
| Ptm: | B-type lamins undergo a series of modifications, such as farnesylation and phosphorylation. Increased phosphorylation of the lamins occurs before envelope disintegration and probably plays a role in regulating lamin associations. | |
| Disease: | Leukodystrophy, demyelinating, autosomal dominant, adult-onset (ADLD) [MIM:169500]: A slowly progressive and fatal demyelinating leukodystrophy, presenting in the fourth or fifth decade of life. Clinically characterized by early autonomic abnormalities, pyramidal and cerebellar dysfunction, and symmetric demyelination of the CNS. It differs from multiple sclerosis and other demyelinating disorders in that neuropathology shows preservation of oligodendroglia in the presence of subtotal demyelination and lack of astrogliosis. {ECO:0000269|PubMed:16951681}. Note=The disease is caused by variants affecting the gene represented in this entry. | |
| Miscellaneous: | The structural integrity of the lamina is strictly controlled by the cell cycle, as seen by the disintegration and formation of the nuclear envelope in prophase and telophase, respectively. | |
| Similarity: | Belongs to the intermediate filament family. {ECO:0000255|PROSITE-ProRule:PRU01188}. | |
