TNF-alfa inducirani protein 8 sličan proteinu 2 (TNFAIP8L2 ili TIPE2) jest protein koji je kod ljudi kodiran genom TNFAIP8L2 sa hromosoma 1. Eksprimiran je prvenstveno u tipovima ljudskih mijeloidnih ćelija i služi kao regulator imunskee kontrolne tačke upala i metabolizma.^[5]

Struktura

Kristalna struktura TIPE2 otkriva da sadrži veliku, hidrofobnu centralnu šupljinu koja je spremna za vezivanje kofaktora.^[7]

Funkcija

TNFAIP8L2 je član porodice TNFAIP8 (protein 8 izazvan faktorom nekroze tumora-α ili TIPE) koji funkcionišu kao transferni proteini za drugoglasničke lipide PIP2 i PIP3. Ostala tri člana porodice su TNFAIP8, TNFAIP8L1 i TNFAIP8L3.^[8]

Klinički značaj

TIPE2 djeluje kao negativan regulator imunskog sistema.^[5]^[9] Podreguliran je kod pacijenata sa infektivnim i autoimunskim bolestima, a djeluje i kao tumorski supresor kod nekoliko tipova raka.^[10] Njegov nokaut dovodi do leukocitoze i sistemskih upalnih poremećaja kod miševa.^[8]^[11]
