Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and histone H3-methyl-lysine-36 demethylase activity. Acts upstream of or within several processes, including animal organ development; cardiac muscle cell contraction; and heterochromatin assembly. Part of protein-containing complex. Is expressed in several structures, including early conceptus; forelimb bud; genitourinary system; gut; and liver. Orthologous to human UTY (ubiquitously transcribed tetratricopeptide repeat containing, Y-linked). [provided by Alliance of Genome Resources, Apr 2022]
