Anti-NEDD4-binding protein 1 N4BP1 Antibody

Nedd4-binding partner-1 (N4BP1) is a developmentally expressed protein interactor and monoubiquitylation substrate of Nedd4, a HECT domain-containing ubiquitin ligase that mediates ubiquitylation and proteasome degradation of target proteins and may have a fundamental role to play in embryonic processes. N4BP1 can undergo Nedd4-mediated polyubiquitylation and proteosomal degradation. N4BP1 also functions as a negative regulator of AIF4 (also known as ITCH or Atrophin-1), an E3-ubiquitin ligase, by interacting with the second WW domain of AIF4 and impairing ubiquitination of substrates.

N4BP1 antibody was raised against a 18 amino acid synthetic peptide near the amino terminus of human N4BP1. The immunogen is located within the first 50 amino acids of N4BP1.

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 (By similarity) . .

N4BP1 antibody can be stored at 4°C for three months and -20°C, stable for up to one year. Avoid repeated freeze-thaw cycles. Antibodies should not be exposed to prolonged high temperatures.

Nucleus, nucleolus . Nucleus, PML body . Primarily localizes to the nucleolus. Also localizes to the PML nuclear bodies, when desumoylated (By similarity) . .
