BTG2 is an anti-proliferative protein. BTG2 modulates transcription regulation mediated by ESR1.The protein encoded by this gene is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. This encoded protein is involved in the regulation of the G1/S transition of the cell cycle.
