Structure of a vertebrate RNA binding domain of telomerase (TRBD)Structure of a vertebrate RNA binding domain of telomerase (TRBD)
Structural highlights
Publication Abstract from PubMedTelomerase is a ribonucleoprotein reverse transcriptase that replicates the ends of chromosomes, thus maintaining genome stability. Telomerase ribonucleoprotein assembly is primarily mediated by the RNA binding domain (TRBD) of the enzyme. Here we present the high-resolution TRBD structure of the vertebrate, Takifugu rubripes (trTRBD). The structure shows that with the exception of the N-terminal linker, the trTRBD is conserved with the Tribolium castaneum and Tetrahymena thermophila TRBDs, suggesting evolutionary conservation across species. The structure provides a view of the structural organization of the vertebrate-specific VSR motif that binds the activation domain (CR4/5) of the RNA component of telomerase. It also reveals a motif (TFLY) that forms part of the T-CP pocket implicated in template boundary element (TBE) binding. Mutant proteins of conserved residues that consist of part of the T and TFLY motifs disrupt trTRBD-TBE binding and telomerase activity and processivity, supporting an essential role of these motifs in telomerase RNP assembly and function. A Motif in the Vertebrate Telomerase N-Terminal Linker of TERT Contributes to RNA Binding and Telomerase Activity and Processivity.,Harkisheimer M, Mason M, Shuvaeva E, Skordalakes E Structure. 2013 Sep 17. pii: S0969-2126(13)00305-5. doi:, 10.1016/j.str.2013.08.013.
