Protein: Germinal-center associated nuclear protein (GANP) (EC 2.3.1.48) (80 kDa MCM3-associated protein) (MCM3 acetylating protein) (MCM3AP) (EC 2.3.1.-) (MCM3 acetyltransferase) (O60318)
Organism: Homo sapiens (Human)
Function: As a component of the TREX-2 complex, involved in the export of mRNAs to the cytoplasm through the nuclear pores. 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.
Subcellular location: [Isoform GANP]: Nucleus envelope {ECO:0000269|PubMed:20005110, ECO:0000269|PubMed:21195085, ECO:0000269|PubMed:22307388, ECO:0000269|PubMed:23591820, ECO:0000269|PubMed:28633435}. Nucleus, nuclear pore complex {ECO:0000269|PubMed:22307388, ECO:0000269|PubMed:23591820}. Nucleus, nucleoplasm {ECO:0000269|PubMed:20005110}. Chromosome {ECO:0000269|PubMed:23652018}. Note=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:22307388, PubMed:23591820). Also found associated with chromatin (PubMed:23652018). In B-cells, targeted to the immunoglobulin variable region genes (PubMed:23652018). {ECO:0000269|PubMed:20005110, ECO:0000269|PubMed:21195085, ECO:0000269|PubMed:22307388, ECO:0000269|PubMed:23591820, ECO:0000269|PubMed:23652018}.; SUBCELLULAR LOCATION: [Isoform MCM3AP]: Cytoplasm {ECO:0000269|PubMed:12226073, ECO:0000269|PubMed:21195085}. Nucleus {ECO:0000269|PubMed:12226073, ECO:0000269|PubMed:21195085}. Note=Translocates into the nucleus in the presence of MCM3 (PubMed:12226073). Associates with chromatin possibly through interaction with MCM3 (PubMed:12226073). {ECO:0000269|PubMed:12226073}.
