Myb-related protein A (also known as A-Myb or MYBL1) is a transcription factor that binds DNA and recognises recognise the sequence 5'-YAAC[GT]G-3' [, ]. It is a component of the DREAM (MuvB/DRM) complex, which represses cell cycle-dependent genes in quiescent cells and plays a role in the cell cycle-dependent activation of G2/M genes [, ].
