The protein regulates the expression of male-specific genes through binding to DNA segments. The DNA binding domain is called HMG-box (High Mobility Group protein) and comprises about 70 residues, with the abundance of aromatic, basic and proline residues. The binding induces severe distortion (kinking) of DNA. In this display, the structures of DNA segment and the HMG-box from 1J46 of PDB are shown. This is my second attempt to use Max/Jitter for 3D graphics.
