Example sentences for: polyglutamine

How can you use “polyglutamine” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Long polyglutamine repeats have been found in a number of transcription factors [ 39 ] . Notably, the C-terminus of murine HMG-box protein SRY contains a large polyglutamine repeat region that is responsible for the sex-determining function of this protein [ 40 ] . However, a number of neurodegenerative disorders, such as Huntington disease and spinobulbar muscular atrophy, are also strongly associated with proteins containing a polyglutamine stretch [ 41 ] . Conformational change and protein misfolding in the expanded polyglutamine region is believed to be the molecular basis of the pathogenesis [ 42 ] . Whether the presence of polyglutamine repeats in the C-terminus of human TNRC9 is important for function or alternatively hinders its ability to form a functional protein remains to be determined.

  • In transfected cells, subdomains of TAF II 135 can act as dominant negative repressors of CREB activity [ [ 26 27 28 ] ]. It has further been suggested that some neurodegenerative diseases may result from sequestration of TAF II 135 by expanded polyglutamine domains and consequent interference with CREB activity [ 29].

  • The inclusions bear a superficial resemblance to those described in some of the polyglutamine disorders, and appear to sequester Hsp70, ubiquitin, importin-β, and glucocorticoid receptor.
