TAP Family: Coactivator p15
Kretzschmar et al (1994): Functional deletion analyses revealed a bipartite structure of p15 comprising an amino-terminal regulatory domain and a carboxy-terminal cryptic DNA-binding domain. We provide evidence that activity of p15 is controlled by protein kinases that target the regulatory domain. Structural and functional similarities, including sequence homology to domains essential for cofactor function, cofactor activity, promiscuity with respect to transcriptional activators, and interactions with components of the basal transcription machinery, relate this novel cellular cofactor to viral immediate-early transcriptional regulators.
