Example sentences for: lxxll
How can you use “lxxll” in a sentence? Here are some example sentences to help you improve your vocabulary:
Phage display techniques have revealed that ERα and ERβ show different preferences in LXXLL binding (reviewed in [ 34 35 ] ). Moreover, some cofactors that contain LXXLL motifs show differential binding to LBDs of the ER isoforms (reviewed in [ 36 ] ). SHP binds ERα preferentially [ 37 ] , and represses ERα activity more strongly than that of ERβ.
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.
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.
The unliganded LBD recognizes hydrophobic motifs, termed interaction domains (IDs), which are reiterated three times in N-CoR and twice in SMRT and conform to the consensus L/IXXIIXXXL [ 4 ] (see also [ 16 ] ). By contrast, the liganded LBD binds shorter hydrophobic motifs termed NR boxes that are reiterated several times within each coactivator and conform to the consensus LXXLL.
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 ] .
