Résumé UniProt
As a component of the TREX-2 complex, involved in the export of mRNAs to the cytoplasm through the nuclear pores (PubMed:20005110, PubMed:20384790, PubMed:23591820, PubMed:22307388). Through the acetylation of histones, affects the assembly of nucleosomes at immunoglobulin variable region genes and promotes the recruitment and positioning of transcription complex to favor DNA cytosine deaminase AICDA/AID targeting, hence promoting somatic hypermutations (PubMed:23652018).
Résumé Entrez
The minichromosome maintenance protein 3 (MCM3) is one of the MCM proteins essential for the initiation of DNA replication. The protein encoded by this gene is a MCM3 binding protein. It was reported to have phosphorylation-dependent DNA-primase activity, which was up-regulated in antigen immunization induced germinal center. This protein was demonstrated to be an acetyltransferase that acetylates MCM3 and plays a role in DNA replication. The mutagenesis of a nuclear localization signal of MCM3 affects the binding of this protein with MCM3, suggesting that this protein may also facilitate MCM3 nuclear localization. This gene is expressed in the brain or in neuronal tissue. An allelic variant encoding amino acid Lys at 915, instead of conserved Glu, has been identified in patients with mild intellectual disability.
Spécificité tissulaire
Widely expressed (PubMed:11024281). Up-regulated in germinal center B-cells in tonsils (at protein level) (PubMed:11024281).
Implication dans la maladie
Peripheral neuropathy, autosomal recessive, with or without impaired intellectual development: An autosomal recessive disorder characterized by early childhood-onset of peripheral sensorimotor neuropathy, progressive distal muscle weakness, atrophy in hands and feet, and gait difficulties, often with loss of ambulation. Most affected individuals also have impaired intellectual development, although some have normal cognition. Additional features may include eye movement abnormalities, claw hands, foot deformities, and scoliosis.
Similitudes de séquence
Belongs to the SAC3 family.
Localisation cellulaire
Nucleus envelope. Nucleus > Nuclear pore complex. Nucleus > Nucleoplasm. Chromosome.
Predominantly located at the nuclear envelope, facing the nucleus interior (PubMed:20005110, PubMed:21195085, PubMed:23591820). Localization at the nuclear pore complex requires NUP153, TPR and ALYREF/ALY (PubMed:23591820, PubMed:22307388). Also found associated with chromatin (PubMed:23652018). In B-cells, targeted to the immunoglobulin variable region genes (PubMed:23652018).
