YY1 (human)

Overview
YY1 a polycomb-group (Pc-G) protein essential for early mammalian development and the regulation of X-inactivation and certain imprinted genes. Required for the transactivation of TSIX by CTCF. The complex of CTCF-YY1-TSIX is a critical regulator of the X chromosome binary switch. Can function as an activator or a repressor depending on the presence of other proteins. For example it acts as a repressor in absence of adenovirus E1A protein but as an activator in its presence. Note: This description may include information from UniProtKB.
