The following text describes a protein:
Function:
E3 SUMO-protein ligase (By similarity). Component of the nuclear pore complex (NPC), a complex required for trafficking across the nuclear envelope. Required for nuclear import of nuclear localization signal (NLS)-containing proteins in an importin alpha/importin beta-dependent manner, but also for the nuclear import of specific proteins such as phosphorylated Mad or the sesquiterpenoid juvenile hormone receptor Met as part of the juvenile hormone signal transduction pathway. Plays a role in nuclear mRNA export by recruiting the mRNA transport complex composed of Nxt1 and sbr/Nxf1 to the NPC. Essential during germline development for transposon silencing and piRNA biogenesis probably by regulating piwi localization to the nucleus. During oogenesis, required to form granules that modulate the biogenesis of annulate lamellae containing nuclear pore complex components.
Subcellular Localization:
Nucleus, nuclear pore complex. Note=Localizes to annulate lamellae, stacked membrane sheets of the endoplasmic reticulum. Localizes to granules which travel from nurse cells into the ooplasm through ring canals connecting the cytoplasm of the two cell types.
Domain:
Contains FG repeats. FG repeats are interaction sites for karyopherins (importins, exportins) and form probably an affinity gradient, guiding the transport proteins unidirectionally with their cargo through the NPC. FG repeat regions are highly flexible and lack ordered secondary structure. The overall conservation of FG repeats regarding exact sequence, spacing, and repeat unit length is limited.
