In red are indicated the copies with an intact 3807 sequence and with an intact promoter.
(1) Based on the HP1 box motif involved in the interaction of ENS-1 with HP1γ: GLPTVRLE.
(2) Coiled-coil(cc) domain defined using the MultiCoil program.
(3) Sequence motif PLIKTEY.
(4) Sequence motif ESVKVTQ, inside the coiled-coil domain.
