Words similar to cofactors
Example sentences for: cofactors
How can you use “cofactors” in a sentence? Here are some example sentences to help you improve your vocabulary:
The Zn-ribbons are widespread, small domains that are comprised of two β-hairpins bounded by consecutive extended regions stabilized by metal-coordinating residues in the hairpin loops [ 67 68 69 70 ] . Zn-ribbons are present in a variety of nucleic-acid-binding proteins, including several ribosomal proteins, translation factors, aminoacyl-tRNA synthetases, RNA polymerase cofactors in archaea and eukaryotes, and several transcription factors.
It will be interesting to see how well Ahab performs in situations where the concerted binding of cofactors constrains the spacing of binding sites [ 13 14 ] .
Cumulatively, however, these observations do suggest a mechanism whereby HIV-1 expression in renal epithelium may induce cyclin D 1 : activation of Src-family kinases by Nef would be expected to up-regulate cyclin D 1 gene expression and promote the synthesis and stabilization of cyclin D 1 protein via Src-Ras-MAPK and Src-PI3K-mTOR signal transduction pathways, respectively [ 32 33 34 ] . Interestingly, our unpublished in vitro observations and published data showing marked expression of basic fibroblast growth factor in the interstitium of HIVAN kidneys [ 35 ] suggest that soluble mitogens may be important cofactors with HIV-1 expression to induce cyclin D 1 . Thus, interrupting HIV-1 gene expression should down-regulate cyclin D 1 and correct the phenotypic abnormalities in infected podocytes.
ERα enhances AP-1 activity in response to estrogens, [ 28 29 ] but ERβ inhibits AP-1 activity in response to estrogens [ 29 30 31 ] . ERβ also completely suppresses ERα activity at the cyclin D1 promoter and even suppresses the activity of an ERα mutant that is selectively superactive at AP-1 sites and CREs [ 29 ] . Finally, ERβ shows a unique capacity to enhance AP-1 activity in response to selective estrogen receptor modulators (SERMs) such as raloxifene, tamoxifen and ICI 182,780/Faslodex (ICI) [ 30 31 32 ] . Together, these observations suggest that there are fundamental differences in the way that the ERs bind unspecified cofactors that modulate gene expression, and that some of these cofactors must play a role in differential ER activity at AP-1 sites.
ERβ might bind to yet more cofactors that contain variant NR boxes that resemble the β-box.
