AP-1 is a heterodimer comprised of bZIP transcription factors typically C-JUN and JUND along with members of the fos (usually c-FOS) and ATF (usually ATF2) families. All bZIP transcription factors contain leucine zippers that enable homo- and heterodimerisation and AP-1 components are organised into JUN-JUN JUN-FOS or JUN-ATF dimers.
