Antibodies against 70-kD heat shock cognate protein inhibit mediated nuclear import of karyophilic proteins
Previously, we found that anti-DDDED antibodies strongly inhibited in vivo nuclear transport of nuclear proteins and that these antibodies recognized a protein of 69 kD (p69) from rat liver nuclear envelopes that showed specific binding activities to the nuclear location sequences (NLSs) of nucleoplasmin and SV-40 large T-antigen. Here we identified this protein as the 70-kD heat shock cognate ...
متن کاملThe 210-kD nuclear envelope polypeptide recognized by human autoantibodies in primary biliary cirrhosis is the major glycoprotein of the nuclear pore.
We have recently reported a new family of nuclear autoantibodies in a subset of patients with primary biliary cirrhosis. These antibodies bind to a nuclear envelope polypeptide(s) of approximately 200 kD, the exact identity of which was not established. In this study, we show that all of these autoantibodies are directed against a 210-kD integral membrane glycoprotein of the nuclear pore.
متن کامل100-kD coated vesicle proteins: molecular heterogeneity and intracellular distribution studied with monoclonal antibodies
Proteins with molecular weights of around 100,000 (designated 100K) are found in all coated vesicles. Five monoclonal antibodies have been raised against the major 100K proteins of bovine brain coated vesicles, which migrate on SDS gels as three closely spaced bands. One antibody stains the middle band (band B), two stain both upper and lower bands (bands A and C), and two stain the lower band ...
متن کاملAntibodies to a 15 kD nuclear antigen in patients with juvenile chronic arthritis and uveitis.
Young girls with a pauciarticular onset of juvenile chronic arthritis and circulating antinuclear antibodies are at risk for chronic uveitis. The actual nuclear antigen for these antinuclear antibodies has not been defined. Conventional laboratory techniques, such as counter immunoelectrophoresis, have shown that antibodies to well defined "extractable nuclear antigens" (eg, RNP, Sm, SS-A, and ...
متن کاملRan-unassisted Nuclear Migration of a 97-kD Component of Nuclear Pore–targeting Complex
A 97-kD component of nuclear pore-targeting complex (the beta-subunit of nuclear pore-targeting complex [PTAC]/importin/karyopherin) mediates the import of nuclear localization signal (NLS)-containing proteins by anchoring the NLS receptor protein (the alpha-subunit of PTAC/importin/karyopherin) to the nuclear pore complex (NPC). The import requires a small GTPase Ran, which interacts directly ...
