Anti-Nuclear Pore Complex Proteins Antibody, clone 414

Nuclear pore glycoprotein p62 (UniProt P17955; also known as 62 kDa nucleoporin, Nucleoporin Nup62) is encoded by the Nup62 gene (Gene ID 65274) in rat species. The nuclear pore complex (NPC) acts as a passageway for nucleocytoplasmic transport. Soluble cargo-protein complexes navigate through the pore by binding to phenylalanine-glycine (FG)-repeat proteins attached to the channel walls. The Nup62 complex is located in the center of the NPC and contains the FG-repeat proteins Nup62, Nup54, and Nup58 associated with each other via conserved coiled-coil segments in a 1:1:1 stiochiometric ratio. The nuclear envelope breaks down during prometaphase. The disassembled nucleoporin subcomplexes act as critical regulators of various mitotic events to ensure proper chromosome segregation. Specifically, Nup62 is reported to localize to centrosomes/spindle poles, where it associates with the centrosomal proteins gamma-tubulin and hSAS-6. Nup62 is involved in the recruitment of critical proteins to the centrosome and its depletion results in mislocalization of several centrosomal components.

Immunoprecipitation Analysis: A representative lot immunoprecipitated three major GlcNAcylated prtoein species of 62, 175, and 270 kDa from SDS-solubilized pore complex-lamina extract of Buffalo rat liver (BRL) cell nuclei preparation that had been labeled with UDP-[3H]Gal by galactosyltransferase (Davis, L.I., and Blobel, G. (1987). Proc. Natl. Acad. Sci. U. S. A. 84(21):7552-755).
Immunoprecipitation Analysis: A representative lot immunoprecipitated GlcNAcylated 62 kDa protein (p62) from the SDS-solubilized pore complex-lamina extract, as well as a less glycosylated p61 cytoplasmic form from the postmitochondrial supernatant of Buffalo rat liver (BRL) cells (7552-755; Davis, L.I., and Blobel, G.
