RNF4, Human (Biotinylated)

RNF4 protein is an E3 ubiquitin protein ligase that can uniquely bind and ubiquitinate polyubiquitination chains, mediating "Lys-6", "Lys-11", "Lys-48" and "Lys- 63"-linked polyubiquitination to promote proteasomal degradation. Its multiple substrates, including PML and PEA3, regulate various cellular processes. RNF4 Protein, Human (Biotinylated) is the recombinant human-derived RNF4, expressed by E. coli, with tag-free.
