engineered PDZ domain (ePDZ)
Usage and Biology
The engineered PDZ domain is a globuar protein domain of 80 - 90 amino acids wich has an enhanced interaction with other proteins. Normally PDZ domains bind to a short region at the C-terminus of other proteins but there are some proteins which recognize internal sequence motifs of target proteins through a single binding site on the domains [1][2]. There are more over 1000 known proteins containing this domain in eucaryotes and bacteria but just a few examples are shown in archea [3].
ePDZ is a crucial part of the blue light-inducible expression system. It is able to bind to the J-alpha-helix of the LOV2 domain. The principle of the light-induced expression is explained here [4].
