Apoptotski faktor aktiviranja proteaze 1, također poznat kao APAF1, je ljudski homolog CED-4 gena C. elegans. To jest protein koji je kod ljudi kodiran genom APAF1 sa hromosoma 12.^[5][6][7]

Funkcija

Protein je identifikovan u laboratoriji Xiaodonga Wanga kao aktivator kaspaze-3 u prisustvu citohroma C i dATP.<.^[8] Ovaj gen kodira citoplazmatski protein koji čini jedno od centralnih čvorišta u regulatornoj mreži apoptoza. Ovaj protein sadrži (sa N terminala) domen za regrutaciju kaspaznog (CARD), ATPazni domen (NB-ARC), nekoliko kratkih spiralnih domena i zatim nekoliko kopija domena zvanog WD40 ponavljanje. Nakon vezivanja citohroma c i dATP, ovaj protein formira oligomerni apoptosom. Apoptosom veže i cijepa prokaspazni-9 protein, oslobađajući njegov zreli, aktivirani oblik. O preciznom mehanizmu za ovu reakciju se još uvijek raspravlja iako rad koji je objavio Guy Salvesen sugerira da apoptosom može inducirati dimerizaciju kaspaza-9 i naknadnu autokatalizu.^[9] Aktivirana kaspaza-9 stimulira kaspaznu kaskadu koja dopušta ćeliju apoptozi.

Alternativna prerada rezultira u nekoliko varijanti transkripta koje kodiraju različite izoforme.^[5]

Struktura

Dužina polipeptidnog lanca je 1.248 aminokiselina, a molekulska težina 141.840 Da.^[5] APAF1 sadrži CARD domen sa motivom sa motivom grčkog ključa koji se sastoji od šest spirala, domena Rossmanovog nabora za vezivanje nukleotida, kratkog spiralnog motiva i domene krilate spirale.^[10]

Interakcije

Pokazalo se da je APAF1 u interakciji sa:

• APIP,^[11]
• BCL2-liki 1 ^[12][13]
• Kaspaza-9,^{[8][11][12][13][14]}
• HSPA4,^[15] i
• NLRP1.^[14]
