Homolog 2 proteina pelino je protein koji je kod ljudi kodiran genom PELI2.^[5]^[6]^[7]

Resch et al. (2001) utvrdili su da se gen PELI2 sastoji od šest egzona. Hibridnom radijacijskom analizom zračenja, mapirali su gen PELI2 u hromosomu 14, sekvenca q21.^[8]^[8]

Pellino proteini, poput PELI2, su međukomponente u urođenim signalnim kaskadama imunskog odgovora koje iniciraju Toll-liki receptori (TLR) i IL1R, a u interakciji su sa homologom Drosophila pelle IRAK1, TRAF6 i NFKB (sažetak Jensen i Whitehead, 2003).

Aminokiselinska sekvenca uredi

Dužina polipeptidnog lanca je 420 aminokiselina, a molekulska težina 46 435 Da.^[9]

Kloniranje i ekspresija uredi

Pretragom baze podataka, Resch et al. (2001) identificirali su mišje i ljudske homologe Drosophila pellino. Ljudski gen PELI2 kodira protein od 420 aminokiselina.

Funkcija gena uredi

Koprecipitacijom i Western blot analizom, Jensen i Whitehead (2003) pokazali su da PELI2 komunicira s proteinima TRAF6 i TAK1 (MAP3K7), oba nizvodno od IRAK1 u kaskadi TLR / IL1R, ali ne i MYD88, uzvodni protein . Međutim, PELI2, ali ne i PELI1, promovirao je aktivaciju JUN-a i ELK1 fosforilacijom JNK-a (MAPK8).^[10]

Koristeći 2-hibridni skrining kvasca za proteine u interakciji s IRAK4 , Strelow et al. (2003) identificirali su PELI2. Analiza imunoprecipitacije pokazala je interakciju sa IRAK1 i IRAK4, nezavisno od aktivnosti njihovih kinaza. PELI2 je fosforiliran putem kinaza aktivnih IRAK1 i IRAK4. Predložili su da bi PELI2 mogao biti molekula skele koja povezuje signalizaciju receptora Toll/interleukin-1 (TIR) sa općim ćelijskim procesima.^[11] Koristeći snimak faga, nakon čega slijedi analiza imunoprecipitacije, Liu et al. (2004) identificirali su PELI2 i SOCS3, kao interaktivne partnere BCL10, što je odgovor na stimulaciju lipopolisaharida (LPS) u TLR putu. Interakcija se odvija preko ostataka 169 do 233 PELI2 i neizravno je blokirana ekspresijom SOCS3.^[12]

Kim et al. (2012) pokazali su da nokdaun PELI2, ali ne i PELI1, ukida IL1 i LPS-induciranu ubikvitinaciju IRAK1 na lys63 i smanjuje ubikvitinaciju preko lys48. PELI2 je također potreban za aktivaciju NFKB-a zavisnu od TAK1. RT-PCR analiza pokazala je da je PELI2 nokdaun smanjio ekspresiju KC (CXCL1), IL6 i TNF induciranu IL1– i LPS-om u mišjim makrofazima u kasnim vremenskim tačkama, praćenu raspadanjem upalnih gena iRNK. Nokdaun je također umanjio aktivaciju JNK i ERK (MAPK3). Zaključili su da PELI2 ima kritičnu ulogu u posttranskripcijskoj kontroli posredovanoj TLR/IL1R-om.^[13]
