CC       thought to provide a framework for the nuclear envelope and may also
CC       interact with chromatin.

CC   -!- SUBCELLULAR LOCATION: Nucleus inner membrane; Lipid-anchor;
CC       Nucleoplasmic side.
CC   -!- PTM: B-type lamins undergo a series of modifications, such as
CC       farnesylation and phosphorylation. Increased phosphorylation of the
CC       lamins occurs before envelope disintegration and probably plays a role
CC       in regulating lamin associations.
CC   -!- DISEASE: Partial acquired lipodystrophy (APLD) [MIM:608709]: A rare
CC       childhood disease characterized by loss of subcutaneous fat from the
CC       face and trunk. Fat deposition on the pelvic girdle and lower limbs is
CC       normal or excessive. Most frequently, onset between 5 and 15 years of
CC       age. Most affected subjects are females and some show no other
CC       abnormality, but many develop glomerulonephritis, diabetes mellitus,
CC       hyperlipidemia, and complement deficiency. Mental retardation in some
CC       cases. APLD is a sporadic disorder of unknown etiology.
CC       {ECO:0000269|PubMed:16826530, ECO:0000269|PubMed:22768673}. Note=The

CC       heterogeneous group of disorders defined by the combination of action
CC       and reflex myoclonus, other types of epileptic seizures, and
CC       progressive neurodegeneration and neurocognitive impairment. EPM9 is an
CC       autosomal recessive form characterized by myoclonus, tonic-clonic
CC       seizures, ataxia, and delayed psychomotor development.
CC       {ECO:0000269|PubMed:25954030}. Note=The disease may be caused by
CC       variants affecting the gene represented in this entry.
CC   -!- MISCELLANEOUS: The structural integrity of the lamina is strictly
CC       controlled by the cell cycle, as seen by the disintegration and
CC       formation of the nuclear envelope in prophase and telophase,
CC       respectively.
CC   -!- SIMILARITY: Belongs to the intermediate filament family.
CC       {ECO:0000255|PROSITE-ProRule:PRU01188}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAH06551.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
