Protein: Neprilysin-2 (EC 3.4.24.11) [Cleaved into: Neprilysin-2, soluble form] (A0A0B4K692)
Organism: Drosophila melanogaster (Fruit fly)
Function: Metalloendoprotease which cleaves peptides such as tachykinin peptide TK-2 at the amino side of hydrophobic residues. Functions in female fertility, embryogenesis and memory formation. Required in females for normal patterns of egg laying, probably due to its function in sperm retention and preventing sperm displacement by rival ejaculates. Also required for normal patterns of hatching due to its important role in early embryonic development. Required in the dorsal paired medial neurons for the proper formation of middle-term memory. Also required in the mushroom body neurons where it functions redundantly with neprilysins Nep3 and Nep4 in normal long-term memory formation.
Subcellular location: Cell membrane {ECO:0000305}; Single-pass type II membrane protein {ECO:0000305}. Secreted {ECO:0000269|PubMed:15554877, ECO:0000269|PubMed:17157960}. Note=A secreted form exists that is probably produced by proteolytic cleavage (Probable). In embryos, adult Malpighian tubules and testes, detected in the soluble fraction but is not detected in the membrane fraction (PubMed:15554877, PubMed:17157960). {ECO:0000269|PubMed:15554877, ECO:0000269|PubMed:17157960, ECO:0000305|PubMed:15554877, ECO:0000305|PubMed:17157960}.
