Example sentences for: scaffold
How can you use “scaffold” in a sentence? Here are some example sentences to help you improve your vocabulary:
The RDRPs of RNA viruses define one major lineage of nucleic acid polymerases, which additionally includes reverse transcriptases, archaeo-eukaryotic DNA polymerases, and nucleotide cyclases [ 8 9 10 11 12 13 ] . The DNA-dependent RNA polymerase of certain bacteriophages, such as T7, and the archaeo-eukaryotic primase (also detected in some bacteria) are divergent derivatives of the same fold [ 11 14 ] . The core catalytic domain of all these enzymes, the so-called "palm" domain, has an RNA-recognition motif (RRM)-like fold with strategically placed metal-coordinating residues, which form the active site [ 11 15 16 ] . In contrast, bacterial DnaG-type primases (also present in archaea and some eukaryotes) contain a polymerase domain of the Rossmann-like TOPRIM fold, which is shared with topoisomerases and OLD-family nucleases [ 17 18 19 ] . The recently solved structures of the DDRPs from yeast and the thermophilic bacterium Thermus thermophilus indicate that the β' subunit (according to the subunit nomenclature of Escherichia coli DDRP, which we hereinafter employ to designate all orthologs of the respective E. coli subunits) of these enzymes defines another distinct catalytic scaffold, which is unrelated to any of the above template-dependent RNA polymerases [ 20 21 22 23 24 ] . Additionally, the structural and evolutionary affinities of two other template-dependent RNA polymerases, namely RDRPs involved in PTGS [ 25 26 27 ] and primases of herpesviruses [ 28 ] , remain obscure.
For example, a 252-kb WGS3 scaffold extends over 13 smaller Release 2 scaffolds, and includes all seven exons of the heterochromatic gene rolled in the correct order and orientation (Figure 3).
They have long GC-rich 5'-UTRs that can form extensive secondary structure and have been classified as "weak" mRNAs because they are translated inefficiently when eIF4E levels are limiting (reviewed in [ 15 ] ). It has been proposed that when eIF4E levels are elevated these mRNAs can more effectively recruit eIF4E and its associated factors including eIF4G, a scaffold protein essential in recruiting the small ribosomal subunit, and eIF4A, a helicase essential for scanning through secondary structures in the 5'-UTR [ 15 27 ] .
However, the question of what plasma membrane-spanning protein serves as the scaffold for Shc binding and beyond remains to be answered.
The DLG5 gene encodes for a protein that is a member of the MAGUK (Membrane Associated Guan late Kinase homologs) family of proteins located in the plasma membrane [ 2 ] . MAGUK is a new family of proteins that act as a molecular scaffold for intracellular signaling pathways [ 11 ] . The MAGUK family of proteins is characterized by domains that interact with other proteins to create an assembly of large multi-protein complexes [ 10 ] . The PDZ (PSD-95, DLG and ZO-1) domains are the best characterized for their binding to the C-terminal region of channels and transmembrane proteins [ 11 ] . Usually each protein has 1-3 copies of such domains [ 8 12 13 ] . The SH3 domain (Src homology 3) are present in proteins that couple transmembrane receptors to signaling molecules [ 14 ] . The presence of this domain in MAGUKs increases their possibilities of interacting with signaling pathways.
