Biological Activity

RING1 belongs to the RING finger family, members of which characterized by a RING domain, a zinc-binding motif related to the zinc finger domain. The protein can bind DNA and can act as a transcriptional repressor. It is associated with the multimeric polycomb group protein complex. RING1 interacts with the polycomb group proteins BMI1, EDR1, and CBX4, and colocalizes with these proteins in large nuclear domains. It interacts with the CBX4 protein via its glycine-rich C-terminal domain. This gene maps to the HLA class II region, where it is contiguous with the RING finger genes FABGL and HKE4.This gene belongs to the RING finger family, members of which encode proteins characterized by a RING domain, a zinc-binding motif related to the zinc finger domain.
