UniprotKB/SwissProt ID: Q9VXE6 (Q9VXE6)
Gene Name:
Nup153
Organism: Drosophila melanogaster (Fruit fly)
Function: Component of the nuclear pore complex (NPC), a complex required for the trafficking across the nuclear envelope (PubMed:17682050). Functions as a scaffolding element in the nuclear phase of the NPC (PubMed:17682050). Essential for the nuclear import of nuclear localization signal (NLS)-containing proteins in a Importin alpha/Importin beta receptor-dependent manner (PubMed:17682050). Required for nuclear import of Mad (PubMed:20547758). Plays a role in chromosomal organization and gene expression regulation; stimulates transcription by promoting the formation of an open chromatin environment (PubMed:20174442). Binds chromatin to nucleoporin-associated regions (NARs) that define transcriptionally active regions of the genome (PubMed:20174442). Associates with extended chromosomal regions that alternate between domains of high density binding with those of low occupancy (PubMed:20174442). Preferentially binds to NARs of the male X chromosome (PubMed:20174442). In males, together with Mgtor, required for the localization of the male-specific lethal (MSL) histone acetyltransferase complex to the X chromosome and therefore for the transcription of dosage compensation genes (PubMed:16543150). May play a role in double strand break DNA repair (PubMed:26502056)
