Human N4BP1 Recombinant Protein (N-His) (GXRP07406)

Human N4BP1 Recombinant Protein (N-His)

Human N4BP1 Recombinant Protein (N-His) is a recombinant protein expressed in E. coli, spanning Met1-Glu193, with an N-terminal His tag. Predicted molecular weight: 23.42 kDa. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. NEDD4-binding protein 1 (N4BP1) is a ~100 kDa protein. Potent suppressor of cytokine production that acts as a regulator of innate immune signaling and inflammation. For research use only.

Acts as a key negative regulator of select cytokine and chemokine responses elicited by TRIF-independent Toll-like receptors (TLRs), thereby limiting inflammatory cytokine responses to minor insults. In response to more threatening pathogens, cleaved by CASP8 downstream of TLR3 or TLR4, leading to its inactivation, thereby allowing production of inflammatory cytokines. Acts as a restriction factor against some viruses, such as HIV-1: restricts HIV-1 replication by binding to HIV-1 mRNAs and mediating their degradation via its ribonuclease activity. Also acts as an inhibitor of the E3 ubiquitin-protein ligase ITCH: acts by interacting with the second WW domain of ITCH, leading to compete with ITCH's substrates and impairing ubiquitination of substrates.
