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

A number of RXR heterodimer complexes have been categorized as either permissive or non-permissive based on their responses to RXR ligands [ 1 ] . Although there are some reported discrepancies, the PPAR, FXR and NGF-IB/NURR1 complexes are generally considered permissive, while the non-permissive group includes the RAR, TR and VDR complexes (see [ 2 3 4 5 6 7 ] ). In the permissive complexes, coactivators can presumably bind to the AF-2 surface of both partners and binding to the RXR partner is stimulated by rexinoid agonists.
ERβ Interactions with N-CoR are Dependent on AF-2 and require H12
It has previously been shown that phosphorylation of the RARγ2 AF-1 is indispensable for primitive endoderm differentiation [ 59].
In other cases, however, the balance of coactivator and corepressor recruitment is regulated by direct competition for the AF-2 surface, rather than ligand-dependent coregulator exchange.
The fact that the mode of ERβ interaction with N-CoR resembles that of NRs with coactivators [ 4 ] , or with corepressors that modulate the activity of liganded NR complexes, such as RIP140 [ 10 ] , raises the possibility that ERβ may be able to recruit N-CoR and SMRT to estrogen-regulated promoters in response to agonists and that the balance of overall ERβ activity in the presence of estrogens may be regulated by competition between p160s and corepressors for the same ERβ AF-2 surface.
