Characterization of CTIP1 interaction with HP1

Creator:: Huddleston, Cortny
Abstract:: COUP-TF interacting protein 1 (CTIP1) is a novel C2H2 zinc finger protein that mediates transcriptional repression of ARP1, a member of the COUP-TF subfamily of orphan nuclear receptors [1]. Here we show that CTIP1 interacts with heterochromatin-associated protein 1 (HP1) in vitro and in cells. This interaction suggests the existence...
