Protein Information (annotations from UniProt)

Database IDHIV0006812
UniProt IDQ99942
Primary gene name(s)RNF5
Synonym gene name(s)G16, NG2, RMA1
Protein nameE3 ubiquitin-protein ligase RNF5
Protein functionHas E2-dependent E3 ubiquitin-protein ligase activity. May function together with E2 ubiquitin-conjugating enzymes UBE2D1/UBCH5A and UBE2D2/UBC4. Mediates ubiquitination of PXN/paxillin and Salmonella type III secreted protein sopA. May be involved in regulation of cell motility and localization of PXN/paxillin. Mediates the 'Lys-63'-linked polyubiquitination of JKAMP thereby regulating JKAMP function by decreasing its association with components of the proteasome and ERAD; the ubiquitination appears to involve E2 ubiquitin-conjugating enzyme UBE2N. Mediates the 'Lys-48'-linked polyubiquitination of TMEM173 at 'Lys-150' leading to its proteasomal degradation; the ubiquitination occurrs in mitochondria after viral transfection and regulates antiviral responses. {ECO:0000269|PubMed:11329381, ECO:0000269|PubMed:12861019, ECO:0000269|PubMed:16176924, ECO:0000269|PubMed:19269966, ECO:0000269|PubMed:19285439}.
Subcellular locationMembrane;
Multi-pass membrane protein. Mitochondrion membrane. Endoplasmic reticulum membrane. Note=Predominantly located in the plasma membrane, with some localization occurring within cytoplasmic organelles.
