Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

| Function | Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for nuclear localization signals (NLS) in cargo substrates. Is thought to mediate docking of the importin/substrate complex to the nuclear pore complex (NPC) through binding to nucleoporin and the complex is subsequently translocated through the pore by an energy requiring, Ran-dependent mechanism. At the nucleoplasmic side of the NPC, Ran binds to the importin, the importin/substrate complex dissociates and importin is re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran. The directionality of nuclear import is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus (By similarity). Mediates the nuclear import of ribosomal proteins RPL23A, RPS7 and RPL5 (PubMed:9687515, PubMed:11682607). In vitro, mediates nuclear import of H2A, H2B, H3 and H4 histones. Binds to CPEB3 and mediates its nuclear import following neuronal stimulation (By similarity). In case of HIV-1 infection, binds and mediates the nuclear import of HIV-1 Rev. |

Background
Nucleocytoplasmic transport, a signal- andenergy-dependent process, takes place through nuclear porecomplexes embedded in the nuclear envelope. The import of proteinscontaining a nuclear localization signal (NLS) requires the NLSimport receptor, a heterodimer of importin alpha and beta subunitsalso known as karyopherins. Importin alpha binds the NLS-containingcargo in the cytoplasm and importin beta docks the complex at thecytoplasmic side of the nuclear pore complex. In the presence ofnucleoside triphosphates and the small GTP binding protein Ran, thecomplex moves into the nuclear pore complex and the importinsubunits dissociate. Importin alpha enters the nucleoplasm with itspassenger protein and importin beta remains at the pore.Interactions between importin beta and the FG repeats ofnucleoporins are essential in translocation through the porecomplex. The protein encoded by this gene is a member of theimportin beta family.
