1 | Leptomycin B inactivates CRM1/exportin 1 by covalent modification at a cysteine residue in the central conserved region. | Cysteine | exportin 1 | Homo sapiens |
2 | Inhibition by N-ethylmaleimide (NEM), an alkylating agent, of CRM1-mediated nuclear export probably was caused by covalent binding of the electrophilic structure in NEM to the sulfhydryl group of Cys-529, because the crm1-K1 mutant showed the normal rate for the export of Rev nuclear export signal-bearing proteins in the presence of not only LMB but also NEM. | Cysteine | exportin 1 | Homo sapiens |
3 | Inhibition by N-ethylmaleimide (NEM), an alkylating agent, of CRM1-mediated nuclear export probably was caused by covalent binding of the electrophilic structure in NEM to the sulfhydryl group of Cys-529, because the crm1-K1 mutant showed the normal rate for the export of Rev nuclear export signal-bearing proteins in the presence of not only LMB but also NEM. | Cysteine | exportin 1 | Homo sapiens |
4 | These results show that the single cysteine residue determines LMB sensitivity and is selectively alkylated by LMB, leading to CRM1 inactivation. | Cysteine | exportin 1 | Homo sapiens |
