Kpna4 Gene Summary [Rat]
Predicted to enable nuclear import signal receptor activity and nuclear localization sequence binding activity. Predicted to be involved in NLS-bearing protein import into nucleus. Predicted to act upstream of with a positive effect on dopamine secretion and gene expression. Predicted to act upstream of or within protein import into nucleus and response to hydrogen peroxide. Predicted to be located in male germ cell nucleus and nuclear membrane. Predicted to be part of NLS-dependent protein nuclear import complex and nuclear pore. Predicted to be active in cytoplasm and nucleoplasm. Orthologous to human KPNA4 (karyopherin subunit alpha 4). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Kpna4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
