Disease relevance of ATF2


High impact information on ATF2

  • Lastly, immune complex protein kinase assays, using [gamma-32P]ATP and activating transcription factor 2 (ATF2) as substrates, showed increased p38 MAP kinase activity from LPS-stimulated human neutrophils [2].
  • Analysis of the fermentation products confirmed that the expression levels of ATF1 and ATF2 greatly affect the production of ethyl acetate and isoamyl acetate [3].
  • Disruption of AYR1 eliminated reductive 17betaHSD activity, and expression of CYP7B on the combination background (atf2, ayr1, TRP(+)) permitted efficient (>98%) bioconversion of DHEA to 7alpha-hydroxyDHEA, a product of potential medical utility [4].
  • In TRP(+) atf2 strains DHEA was then converted to androstene-3beta,17beta-diol (A/enediol) by an endogenous 17beta-hydroxysteroid dehydrogenase (17betaHSD) [4].
  • In addition, a toxic effect of pregnenolone linked to the disruption of ATF2 was observed [5].

Biological context of ATF2


Associations of ATF2 with chemical compounds


Other interactions of ATF2

  • Our results suggest that Atf2p (APAT) plays an active role in the detoxification of 3beta-hydroxysteroids in association with the efflux pumps Pdr5p and Snq2p [5].
  • Sli1p has weak similarity to Atf1p and Atf2p, which are alcohol acetyltransferases [9].
