Target Full Name

Prelamin-A/C

Target 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. Lamin A and C are present in equal amounts in the lamina of mammals. Recruited by DNA repair proteins XRCC4 and IFFO1 to the DNA double-strand breaks (DSBs) to prevent chromosome translocation by immobilizing broken DNA ends. Plays an important role in nuclear assembly, chromatin organization, nuclear membrane and telomere dynamics. Required for normal development of peripheral nervous system and skeletal muscle and for muscle satellite cell proliferation. Required for osteoblastogenesis and bone formation. Also prevents fat infiltration of muscle and bone marrow, helping to maintain the volume and strength of skeletal muscle and bone. Required for cardiac homeostasis.; Prelamin-A/C can accelerate smooth muscle cell senescence. It acts to disrupt mitosis and induce DNA damage in vascular smooth muscle cells (VSMCs), leading to mitotic failure, genomic instability, and premature senescence.

Target Involvement

Emery-Dreifuss muscular dystrophy 2, autosomal dominant (EDMD2); Emery-Dreifuss muscular dystrophy 3, autosomal recessive (EDMD3); Cardiomyopathy, dilated 1A (CMD1A); Lipodystrophy, familial partial, 2 (FPLD2); Limb-girdle muscular dystrophy 1B (LGMD1B); Charcot-Marie-Tooth disease 2B1 (CMT2B1); Hutchinson-Gilford progeria syndrome (HGPS); Cardiomyopathy, dilated, with hypergonadotropic hypogonadism (CMDHH); Mandibuloacral dysplasia with type A lipodystrophy (MADA); Lethal tight skin contracture syndrome (LTSCS); Heart-hand syndrome Slovenian type (HHS-Slovenian); Muscular dystrophy congenital LMNA-related (MDCL)

Target Subcellular Location

Nucleus. Nucleus envelope. Nucleus lamina. Nucleus, nucleoplasm. Nucleus matrix. Note=Farnesylation of prelamin-A/C facilitates nuclear envelope targeting and subsequent cleavage by ZMPSTE24/FACE1 to remove the farnesyl group produces mature lamin-A/C, which can then be inserted into the nuclear lamina. EMD is required for proper localization of non-farnesylated prelamin-A/C.; [Isoform C]: Nucleus speckle.

Target Protein Families

Intermediate filament family

Target Tissue Specificity

In the arteries, prelamin-A/C accumulation is not observed in young healthy vessels but is prevalent in medial vascular smooth muscle cells (VSMCs) from aged individuals and in atherosclerotic lesions, where it often colocalizes with senescent and degener

Target Background

The protein encoded by this gene is part of the nuclear lamina, a two-dimensional matrix of proteins located next to the inner nuclear membrane. The lamin family of proteins make up the matrix and are highly conserved in evolution. During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are thought to be involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. Alternative splicing results in multiple transcript variants. Mutations in this gene lead to several diseases: Emery-Dreifuss muscular dystrophy, familial partial lipodystrophy, limb girdle muscular dystrophy, dilated cardiomyopathy, Charcot-Marie-Tooth disease, and Hutchinson-Gilford progeria syndrome.
