摘　　要：MYB proteins are transcription factors present in all eukaryotes, sharing a common DNA-binding domain that consists of one to three imperfect helix-helix-turn-helix repeats of about 50 amino acids, called R1, R2, and R3 respectively . In animals and yeast these proteins represent a small gene family . Animal RIR2R3-MYB proteins have been described for their role in cell cycle regulation mainly at the G1/S, but also at the G2/M transition, as firstly demonstrated in Drosophila .
