Specificity / Sensitivity
NAE1/APPBP1 (D9I4Z) Rabbit mAb recognizes endogenous levels of total NAE1/APPBP1 protein. This antibody does not cross-react with E1 activating enzymes for either ubiquitin or other ubiquitin-like proteins.
Species Reactivity:
Human, Mouse, Rat, Monkey
The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.
Species predicted to react based on 100% sequence homology:
Bovine, Dog
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala179 of human NAE1/APPBP1 protein.
Background
Similar to ubiquitin, NEDD8 is covalently linked to target proteins through an enzymatic cascade composed of NEDD8-specific E1 (activating)- and E2 (conjugating)-enzymes (1,2). The E2 ligase specific for NEDD8 is Ubc12 (3-5). Ubc12 forms a heterodimeric conjugate with NEDD8 in order to catalyze the transfer of NEDD8 from E1 to lysine side chains of target proteins (1,2). Well known targets of NEDD8 are cullin-based RING E3 ligases. Neddylation of cullin isoforms activates the related ubiquitin E3 complex by promoting its interaction with a cognate ubiquitin-E2 ligase (6-7). Neddylation of Cul-1 complexes containing βTrCP and SKP2 has been shown to be required for controlling the stability of important signaling targets such as IκB, NF-κB, and p27 Kip (8-10), thereby regulating cell cycle progression, signaling cascades, and developmental programming processes (11).
NAE1/APPBP1 (NEDD8-Activating Enzyme 1/Amyloid Beta Precursor Protein Binding Protein 1) exists in a heterodimeric complex with UBA3. This complex functions as an E1 NEDD8-activating enzyme, which utilizes ATP to adenylate the C-terminal glycine of NEDD8 (12-14). Research studies suggest that inhibition of the APPBP1-UBA3 complex may be of therapeutic value for the treatment of human cancers (15,16).
