Our Abpromise guarantee covers the use of ab4977 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and human nicastrin, catalog ab3444. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~ 70-fold) for competitive inhibition of antibody-protein binding reactions.

FunctionEssential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). It probably represents a stabilizing cofactor required for the assembly of the gamma-secretase complex.
Tissue specificityWidely expressed.
Sequence similaritiesBelongs to the nicastrin family.
Cellular localizationMembrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
