Cysteine S-methyltransferase NleE

UniProtKB accession:  Q7DBA6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Cysteine methyltransferase effector that inhibits host cell NF-kappa-B activation by preventing nuclear translocation of host protein RELA/p65. Acts by mediating cysteine methylation of host proteins TAB2 and TAB3: methylation of a conserved cysteine residue of the RanBP2-type zinc finger (NZF) of TAB2 and TAB3 disrupts zinc-binding, thereby inactivating the ubiquitin chain-binding activity of TAB2 and TAB3, leading to NF-kappa-B inactivation. Also mediates cysteine methylation of host protein ZRANB3, inactivating its ability to bind ubiquitin chains.
