Rare case s of carcinoids, thyroid cancer along with rare case of endometrial, lung and pancreatic cancer displayed strong cytoplasmic and nuclear staining. A few cases of testicular and lung cancers were moderately positive. Remaining cancer tissues were weakly stained or negative.
Fraction of cells in a few squamous cell carcinomas along with a single duct carcinoma of breast, high grade glioma and urothelial cancer showed strong cytoplasmic immunoreactivity. Remaining cancer tissues were negative.

Entrez gene summary
The transport of protein and large RNAs through the nuclear pore complexes (NPC) is an energy-dependent and regulated process. The import of proteins with a nuclear localization signal (NLS) is accomplished by recognition of one or more clusters of basic amino acids by the importin-alpha/beta complex; see MIM 600685 and MIM 602738. The small GTPase RAN (MIM 601179) plays a key role in NLS-dependent protein import. RAN-binding protein-16 is a member of the importin-beta superfamily of nuclear transport receptors.[supplied by OMIM, Jul 2002]
