However they added the caution that " As the in vitro phosphorylation and dephosphorylation of GSTHY5 may not be 100% efficient, the observed difference in COP1 binding capacity between the phosphorylated and dephosphorylated forms of GSTHY5 is very likely to be an underestimation". hy5-cop1-7 809756 n/a 809759 unspecified role unspecified role prey prey region required to bind necessary binding region required to bind certain certain sequence position certain certain certain sequence position certain false n/a 809758 unspecified role unspecified role bait bait physical association physical association false false false Figure 4A hy5-dna-1 809757 n/a 809759 unspecified role unspecified role prey prey region gst tag glutathione s tranferase tag glutathione S-tranferase tag glutathione S-tranferase tag gst tag undetermined undetermined sequence position undetermined undetermined undetermined sequence position undetermined false ecoli Escherichia coli (strain K12) n/a 809760 unspecified role unspecified role bait bait direct interaction direct interaction false false false Figure 4B The authors concluded " unphosphorylated HY5 is more effective in binding to these promoters".
