ITCH/AIP4 protein is an E3 ubiquitin protein ligase that catalyzes the conjugation of “Lys-29”, “Lys-48” and “Lys-63” linked ubiquitin, affecting inflammatory signaling pathways. It forms a ubiquitin editing complex that promotes RIPK1 degradation and terminates TNF- or LPS-mediated NFKB1 activation. ITCH/AIP4 Protein, Human is the recombinant human-derived ITCH/AIP4 protein, expressed by E. coli , with tag free.

ITCH/AIP4 functions as an E3 ubiquitin-protein ligase, orchestrating the transfer of ubiquitin from an E2 ubiquitin-conjugating enzyme to targeted substrates, catalyzing 'Lys-29,' 'Lys-48,' and 'Lys-63'-linked ubiquitin conjugation. It plays a crucial role in the regulation of inflammatory signaling pathways, forming an integral part of a ubiquitin-editing protein complex that modulates the transient nature of inflammatory responses. The complex, including TNFAIP3, TAX1BP1, and RNF11, ensures the termination of TNF- or LPS-mediated activation of NFKB1 by deubiquitinating 'Lys-63' polyubiquitin chains on RIPK1 and catalyzing the formation of 'Lys-48'-polyubiquitin chains. ITCH/AIP4 also ubiquitinates various proteins involved in immune response regulation, transcriptional activity modulation, and cellular antiviral responses. Notably, it participates in the degradation of proteins such as JUN, JUNB, and MAVS, highlighting its diverse roles in cellular processes, including apoptosis, reactive oxygen species regulation, and antiviral defense.
