  • Biology-Online • View topic - When does photolysis occur?
    the reaction center come originally from the photolysis Two more questions Do photosystems share the light energy or each antenna complex of the systems collects the light energy separately Is it correct to say that when photosynthesis begins the antenna complex absorbs the light enery or a photon and passes it to the reaction center Two electrons from water then are excited and travel through the electron transport chain blah

  • Biology-Online • View topic - Hepatocyte Nuclear Factor HNF4a
    regulation of a gene in the liver known to be a target of HNF4α this gene is strongly upregulated in HNF4α liver specific KO mice in an inflammatory context LPS My hypothesis is that during inflammation HNF4α is phosphorylated so its DNA binding activity is decreased and the transcription of my gene is not anymore inhibited by HNF4α So I would like to study the phosphorylation status of HNF4α in my case but I really don t know which precise phosphorylation I need to look serin or threonin localization Do you know a good antibody to do this by Western Blot Thank you for your help Aurelie Reply with quote claudepa claudepa Posts 27 Joined Tue Nov 03 2015 12 43 pm Re Hepatocyte Nuclear Factor HNF4a Mon Feb 15 2016 5 48 pm Hi Only by curiosity could it be also the opposite HNF4 could be dephosphorylated during inflamation I believe it is not the phosphate by itself which modifies the affinity for the promotor but the structural change of the transcription factor due to phosphorylation or dephosphorylation which makes that it does not bind anymore to the promotor I suppose that using 32P it is possible to identify
