There's no vaccine to prevent HIV infection and no cure for AIDS. But it's possible to protect yourself and others from infection. That means educating yourself about HIV and avoiding any behavior that allows HIV-infected fluids â blood, semen, vaginal secretions and breast milk â into your body.hen used to help prevent HIV infection, Truvada is only appropriate if your doctor is certain you don't already have an HIV infection. Your doctor should also test for hepatitis B infection. If you have hepatitis B, your doctor should test your kidney function before prescribing Truvada.
Contact Us. A promoter is a regulatory region of DNA located upstream (towards the 5' region) of of a gene, providing a control point for regulated gene transcription.
After the transcription factor binds the DNA, co-regulatory molecules will bind the transcription factor. As with the DBD, transcription factors do not bind to just any co-regulatory proteins.The TAD region of the transcription factor interacts with co-regulatory proteins and it too, has unique sequences.These sequences are only recognized by certain co-regulatory proteins.n summary, transcription factors regulate gene expression. They do this by interacting directly with a target gene through the DBD. Once the transcription factor binds to DNA, co-regulatory molecules bind the transcription factor at the TAD.
