Example sentences for: lxxll
How can you use “lxxll” in a sentence? Here are some example sentences to help you improve your vocabulary:
A mutation (PL T IRML>PL L IRML) that restores the LXXLL consensus increases ERβ binding to N-CoR and permits ERα to bind to N-CoR in the presence of estrogens in mammalian two-hybrid assays.
Thus, some of the observed ERβ specificity is probably a consequence of an unexpected ability to tolerate the absence of a leucine residue at the N-terminus of the LXXLL motif.
Thus, the unusual sequence of the β-box contributes to ERβ specificity and ERβ can tolerate the absence of a conserved N-terminal leucine in LXXLL motifs.
This sequence does not exactly conform to the LXXLL consensus, but contains features (underlined) that resemble the ERβ H12 region (L L LE ML ), and artificial ERβ interacting LXXLL peptides (293, P NLIS LLS ; D47, PL LLS LLS ), both of which bind to the ERβ AF-2 surface [ 43 44 45 46 47 ] . Moreover, the presence of a proline residue amino-terminal to the hydrophobic groups is typical of so-called class II LXXLL motifs which are found in ERβ interacting cofactors such as TRAP220 and RIP140 [ 45 ] . Finally, the unusual C-terminal hydrophobic pair (ML) has been observed in ERα and ERβ H12 [ 43 44 48 ] , and in RIP140 NR boxes [ 19 ] .
Structure-function analysis of the NCoAs have revealed multiple copies of a signature motif, LXXLL, with conserved spacing that is required for interaction with nuclear receptors and CBP/p300 [ 99 101 ] . Intriguingly, different LXXLL motifs are required for PPARγ (Peroxisome Proliferator activated receptor γ, a gene down-regulated in Tat expressing cells; Acc# L07592, Table 1) function in response to different classes of ligands, suggesting distinct configuration of assembled complexes.
