Pcgf3 - polycomb group ring finger 3

Predicted to enable metal ion binding activity. Involved in histone H2A-K119 monoubiquitination and inactivation of X chromosome by genetic imprinting. Part of PcG protein complex. Colocalizes with X chromosome. Is expressed in several structures, including branchial arch; central nervous system; limb; otocyst; and urinary system. Orthologous to human PCGF3 (polycomb group ring finger 3). [provided by Alliance of Genome Resources, Apr 2022]
