STRUCTURE OF THE EQUINE INFECTIOUS ANEMIA VIRUS TAT PROTEIN
Overview
Trans-activator (Tat) proteins regulate the transcription of lentiviral, DNA in the host cell genome. These RNA binding proteins participate in the, life cycle of all known lentiviruses, such as the human immunodeficiency, viruses (HIV) or the equine infectious anemia virus (EIAV). The consensus, RNA binding motifs [the trans-activation responsive element (TAR)] of, HIV-1 as well as EIAV Tat proteins are well characterized. The structure, of the 75-amino acid EIAV Tat protein in solution was determined by two-, and three-dimensional nuclear magnetic resonance methods and molecular, dynamics calculations. The protein structure exhibits a well-defined, hydrophobic core of 15 amino acids that serves as a scaffold for two, flexible domains corresponding to the NH2- and COOH-terminal regions. The, core region is a strictly conserved sequence region among the known Tat, proteins. The structural data can be used to explain several of the, observed features of Tat proteins.
