BACKGROUND
Polycomb group (PcG) proteins form multiprotein complexes that regulate
expression patterns of developmental and cell proliferation genes. Several
members of the PcG contain ring finger domains and are identified as a subclass
of RING finger proteins. The RING-type zinc finger motif is present in a
number of viral and eukaryotic proteins and is made of a conserved cysteinerich
domain that is able to bind two zinc atoms. Proteins that contain the
RING-type zinc finger conserved domain are generally involved in the ubiquitination
pathway of protein degradation. PCGF6 (polycomb group ring finger
6), also known as MBLR or RNF134, is a 350 amino acid nuclear protein
that is ubiquitously expressed and contains one RING-type zinc finger. PCGF6
acts as a transcriptional repressor and regulates the level of histone
H3K4Me3 by activating SmcY histone demethylase. PCGF6 exists as two
alternatively spliced isoforms.
