mago | Protein mago nashi; Core component of the splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junctions on mRNAs. Involved in exon definition of genes containing long introns, including the rolled/MAPK gene. The mago-tsu heterodimer interacts with the EJC key regulator Pym leading to EJC disassembly in the cytoplasm. Has a role in oskar mRNA localization to the posterior pole of the developing oocyte, and may also be involved in polarization of the oocyte microtubule cytoskeleton. (147 aa) | ||||
Nup93-1 | Nuclear pore complex protein Nup93-1; Required for nuclear pore complex assembly, maintenance and function. Required for nuclear import of phosphorylated Mad via importin msk. Has no role in classical nuclear localization signal (cNLS)-dependent nuclear import via importin-beta. Together with Nup62 and Nup154, contributes to karyosome morphology and chromatin organization including attachment to the nuclear envelope in oocytes and nurse cells ; Belongs to the nucleoporin interacting component (NIC) family.
