InterPro maps the Importin-beta_N domain (IPR001494) to small GTPase binding and intracellular protein transport. The GTPase binding annotation is appropriate for karyopherin-beta family members, but intracellular protein transport is misleading for an RNA export receptor.

TreeGrafter correctly identifies this protein as an RNA-binding nuclear transport receptor localized to nucleus, cytoplasm, and the RNA nuclear export complex, consistent with Exportin-5 biology.

Combined IEA methods assign nuclear export signal receptor activity and protein export from nucleus, both of which are CRM1/Exportin-1 functions rather than Exportin-5 functions. These annotations appear to arise from the shared XPO1/5 InterPro superfamily classification.

Identifies B4MAQ2 as an Exportin-5-like protein based on domain architecture and family classification, with predicted function in RanGTP-dependent nuclear export of structured RNAs.

Notes that in Drosophila, Exportin-5 compensates for the absence of canonical Exportin-t, serving as the major tRNA export factor.

No gene-specific literature exists for Dvir\GJ15622; function is inferred entirely from conserved family and domain assignments.

UniProt classifies the protein in the exportin family with Importin-beta_N, Exportin-1/Importin-b-like, and Exportin-5_C domains.

PANTHER subfamily assignment is EXPORTIN-5 (PTHR11223:SF3), distinguishing it from EXPORTIN-1/CRM1.
