General annotation (Comments)

Function	Interacts with centromeric heterochromatin in chromosomes and binds to a specific subset of alphoid satellite DNA, called the CENP-B box. May organize arrays of centromere satellite DNA into a higher order structure which then directs centromere formation and kinetochore assembly in mammalian chromosomes.
Subunit structure	Homodimer. Ref.5
Subcellular location	Nucleus. Centromere.
Sequence similarities	Contains 1 HTH CENPB-type DNA-binding domain. Contains 1 HTH psq-type DNA-binding domain.
