Recombinant Human E3 ubiquitin-protein ligase RNF5 (RNF5), Truncated

Uniprot Id

Q99942

Target Species

Human

Target Name

RNF5

Target Full Name

E3 ubiquitin-protein ligase RNF5

Target Function

Has 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 STING1 at 'Lys-150' leading to its proteasomal degradation; the ubiquitination occurs in mitochondria after viral transfection and regulates antiviral responses.

Target Subcellular Location

Membrane; Multi-pass membrane protein. Mitochondrion membrane. Endoplasmic reticulum membrane. Note=Predominantly located in the plasma membrane, with some localization occurring within cytoplasmic organelles.

Target Tissue Specificity

Widely expressed.

Target Synonyms

RNF5; G16; NG2; RMA1; E3 ubiquitin-protein ligase RNF5; Protein G16; RING finger protein 5; RING-type E3 ubiquitin transferase RNF5; Ram1 homolog; HsRma1

Target Background

The protein encoded by this gene contains a RING finger, which is a motif known to be involved in protein-protein interactions. This protein is a membrane-bound ubiquitin ligase. It can regulate cell motility by targeting paxillin ubiquitination and altering the distribution and localization of paxillin in cytoplasm and cell focal adhesions.
