Example sentences for: af-

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

  • In the case of the RARγ2, degradation requires a constitutive phosphorylation of the AF-1 domain, heterodimerisation with RXR, and the presence of ligand indicating that the receptor has to be transcriptionally active to be degraded [ 42].

  • 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 ] .

  • Preliminary evidence suggests preferred ligands for PPAR activation are 18 C and 20 C FAs, as FAs shorter than 14 C or longer than 20 C will not fit correctly into the PPAR binding pocket and stabilize the AF-2 helix [ 17 ] . The net effect would be that PPAR co-activators are not recruited to relax nucleosomal DNA and allow transcription machinery to interact with various promoter elements.

  • Moreover, other mutations in the upper part of the H3-H5 region that comprises the AF-2 surface (D303Y, I310R and K314A on H3; V328R and L331R on H5) abolished ERβ interaction with both cofactors.

  • ERβ Interactions with N-CoR are Dependent on AF-2 and require H12
