lamin a การใช้

• Lamin A, or LMNA, has already been linked to six other diseases.
• The lamin A / C gen is associated to various diseases.
• LA are considered homologous to lamin A and LIII as a B-type lamin.
• Consequently, no mature lamin A is formed, and a phosphorylated.
• Lamin A constitutes a major structural component of the differentiation via the Notch signaling pathway.
• This allows lamin A to dissociate from the nuclear envelope membrane and fulfill nuclear functions.
• Lamin A is further processed to remove the last 15 amino acids and its farnesylated cysteine.
• Lamin A and B can also bind core histones through a sequence element in their tail domain.
• This study revealed that progeria patients have a defect in the Lamin A gene on chromosome 1.
• The resulting protein, now lamin A, is no longer membrane-bound, and carries out functions inside the nucleus.
• In the truncated lamin A precursor, this cleavage is not possible and the prelamin A cannot mature.
• Mutations in lamin A ( LMNA ) cause Hutchinson Gilford progeria syndrome, a dramatic form of premature aging.
• Lamin A cannot be produced, and prelamin A builds up on the nuclear membrane, causing a characteristic nuclear blebbing.
• In HGPS, the recognition site that the enzyme requires for cleavage of prelamin A to lamin A is mutated.
• Biogenesis of lamin A in normal cells and the failure to generate mature lamin A in Hutchinson Gilford progeria syndrome.
• Biogenesis of lamin A in normal cells and the failure to generate mature lamin A in Hutchinson Gilford progeria syndrome.
• Collins and his co-authors found the mutation on a gene called lamin A in DNA specimens from 18 of 20 progeria patients.
• Lamin A is targeted to the nuclear membrane by an isoprenyl group but it is cleaved shortly after arriving at the membrane.
• HGPS is caused by sporadic mutations ( not inherited from parent ) in the " LMNA " gene, which encodes for lamin A.
• Normally, lamin A is recognized by ZMPSTE24 ( FACE1, a metalloprotease ) and cleaved, removing the farnesol and a few other amino acids.
