Bcl-2 (B-ćelijski limfom 2) je član familije proteinskih regulatora apoptoze. On je kodiran genom.[1][2] -2 je drugi član niza proteina koji su inicijalno bili opisani u kontekstu hromozomske translokacije hromozoma 14 i 18 kod folikularnih limfoma. ortolozi[3] postoje kod mnogobrojnih sisara. Dve izoforme , Izoforma 1, takođe poznata kao , i Izoforma 2, poznata kao , imaju sličnu prostornu strukturu. Međutim, one se razlikuju u njihovoj sposobnosti vezivanja BAD u BAK proteina, kao i po strukturnoj topologiji i elektrostatičkom potencijalu vezujućeg žljeba. Iz toga sledi da Bcl-2 izoforme imaju različite antiapoptotičke aktivnosti.[4]
