Aspartyl aminopeptidase is an enzyme that in humans is encoded by the DNPEP gene.[1][2]

The protein encoded by this gene is an aminopeptidase which prefers acidic amino acids, and specifically favors aspartic acid over glutamic acid. It is thought to be a cytosolic protein involved in general metabolism of intracellular proteins.[2]

Model organisms[edit]

Model organisms have been used in the study of DNPEP function. A conditional knockout mouse line called Dnpeptm1e(EUCOMM)Wtsi was generated at the Wellcome Trust Sanger Institute.[3] Male and female animals underwent a standardized phenotypic screen[4] to determine the effects of deletion.[5][6][7][8] Additional screens performed: - In-depth immunological phenotyping[9]
