Protein attributes

Sequence length	127 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Required, together with Trl, for maintaining the repressed state of target genes including homeotic genes Scr and Ubx. May also be involved in the activation of homeotic genes. Binds to a DNA Polycomb response element (PRE) at the bithorax complex. Also binds to polytene chromosomes at several hundred sites, many of which are shared with Trl and ph-p. Required during embryonic development. Ref.5 Ref.6
Subunit structure	The BTB domain interacts with the BTB domain of Trl in vitro. Found in a Pc-containing complex. Ref.5 Ref.6
Subcellular location	Nucleus. Ref.6
Sequence similarities	Contains 1 BTB (POZ) domain.
