Research:
My project involves delineating the biochemical mechanism(s) by which P-TEFb is mobilized from the 7SK snRNP nuclear complex upon T cell receptor activation of CD4+ T lymphocytes. I'm also interested in understanding how, after its mobilization, P-TEFb becomes recruited to the HIV LTR to facilitate processive transcription of the latent provirus. |
