Example sentences for: lxxll
How can you use “lxxll” in a sentence? Here are some example sentences to help you improve your vocabulary:
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.
Intriguingly, the β-box contains N-terminal proline and C-terminal serine residues that extend the homology of this region to an artificial ERβ-specific peptide [ 45 ] . However, the β-box also lacks the first Leu of the consensus LXXLL.
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.
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.
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.
