SPECIES REACTIVITY:Human, Mouse
HOMOLOGY:Predicted species reactivity based on immunogen sequence: Rat: (78%)
TESTED APPLICATIONS:ELISA, IF, IHC-P, WB
APPLICATIONS:ERAP1 antibody can be used for detection of ERAP1 by Western blot at 1 - 2 μg/ml.
USER NOTE:Optimal dilutions for each application to be determined by the researcher.
POSITIVE CONTROL:1) Cat. No. 1220 - SK-N-SH Cell Lysate

Background

BACKGROUND:The endoplasmic reticulum (ER) aminopeptidase 1 (ERAP1), a member of the peptidase M1 family, plays a central role in peptide trimming, a step required for the generation of most HLA class I-binding peptides (1,2). It is also designated as adipocyte-derived leucine aminopeptidase (A-LAP), puromycin-insensitive leucine-specific aminopeptidase (PILS-AP) and aminopeptidase regulator of TNFR1 shedding (ARTS-1) (3). ERAP1 is localized to the lumen of the ER and induced by interferon. It may be involved in the regulation of blood pressure through the inactivation of angiotensin II and/or the generation of bradykinin in the kidney (3,4).
