Protein Name: Aminopeptidase B
UniprotKB/SwissProt ID: Q9H4A4 (Q9H4A4)

Gene Name: RNPEP

Organism: Homo sapiens (Human)

Function: Exopeptidase which selectively removes arginine and/or lysine residues from the N-terminus of several peptide substrates including Arg(0)-Leu-enkephalin, Arg(0)-Met-enkephalin and Arg(-1)-Lys(0)-somatostatin-14. Can hydrolyze leukotriene A4 (LTA-4) into leukotriene B4 (LTB-4) (By similarity)

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Secreted
