Aminopeptidazni regulator tipa 1 receptorskog faktora tumorske necroze, znan i kao endoplazmatskoretikulumska aminopeptidaza 1 (ARTS-1), jest protein koji je kod ljudi kodiran genom ARTS-1.^[5]

Endoplazmatskoretikulumska aminopeptidaza 1 je aktivna u endoplazmatskom retikulumu, koji je uključen u obradu i transport proteina. Ovaj protein je aminopeptidaza, enzim koji cijepa peptide na N-terminalu na manje fragmente koji se nazivaju aminokiseline.

Nomenklatura

ARTS1 je takođe poznat kao:

ER aminopeptidaza 1 (ERAP1), naziv gena koji je prihvatio Odbor za nomenklaturu Hugo^[6]

Funkcija

ERAP1 ima dvije glavne funkcije u imunskom sistemu:

Prvo, ERAP1 cijepa nekoliko proteina koji se nazivaju citokinskim receptorima na površini ćelija. Cijepanje ovih receptora smanjuje njihovu sposobnost da prenose hemijske signale u ćeliju, što utiče na proces upale.
Drugo, ERAP1 skračuje peptide unutar endoplazmatskog retikuluma, tako da se mogu učitati u glavni kompleks histokompatibilnosti (MHC) klase I. Ovi peptidi su vezani za MHC klasu I u endoplazmatskom retikulumu i eksportirani na ćelijsku površinu, gdje se prezentiraju u imunskom sistemu. Ako imunski sistem prepozna peptide kao strane (kao što su virusni ili bakterijski peptidi), reagira aktiviranjem zaražene ćelije na samouništenje.^[9]

ARTS-1 je član M1 cinkove porodice metaloproteinaza koji djeluje kao aminopeptidaza za razgradnju oligopeptida, cijepanjem počevši od N-terminala. Jedna od funkcija aminopeptidaza je razgradnja potencijalno toksičnih peptida u citosolu.^[5]

ARTS-1 je transmembranski protein koji je lokaliziran na endoplazmatski retikulum. Bio je uključen u sljedeće funkcije:

Izbacivanje različitih receptora citokina i receptora mamaca
Skraćivanje antigenih peptida prije vezivanja za MHC klasa I, što utiče na prezentaciju antigena u citotoksičnim T-limfocitima
Stimulacija fagocitoza nakon oslobađanja od strane makrofaga^[10]

Klinički značaj

Aminopeptidaze imaju ulogu u metabolizmu nekoliko peptida koji mogu biti uključeni u krvni pritisak i patopatogenezu esencijalne hipertenzije.^[5] Mutacije u ARTS-1 povezane su s povećanim rizikom od ankilozantnog spondilitisa, ali samo u HLA-B27 pozitivnih pacijenata.^[11]

Protein kodiran ovim genom je aminopeptidaza uključena u podrezivanje prekursora za vezivanje HLA klase I, tako da se mogu prezentirati na molekulama MHC klase I. Kodirani protein djeluje kao monomer ili kao heterodimer ERAP2. Ovaj protein također može biti uključen u regulaciju krvnog pritiska, inaktivacijom angiotenzina II. Za ovaj gen su pronađene tri varijante transkripta koje kodiraju dvije različite izoforme.^[5]
