Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in negative regulation of chondrocyte differentiation and negative regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; embryonic skeletal system development; and intestinal epithelial cell development. Orthologous to human NKX3-2 (NK3 homeobox 2). [provided by Alliance of Genome Resources, Apr 2022]
