dimerization/histidine phosphotransfer-like (DHpL) domain
Protein DomainThe dimerization/histidine phosphotransfer-like (DHpL) domain is a regulatory domain element within the blue-light-responsive histidine kinase EL346. Structural evidence indicates that, in the dark, interactions involving the LOV sensor domain and the DHpL domain stabilize an inhibited kinase conformation and suppress dimerization, while photoactivation weakens these contacts to promote activation.
