InterPro domain: IPR044825

This entry represents a group of plant transcriptional activators, including GLK1/2 and APRR2 from Arabidopsis. GLK1 functions with GLK2 to promote chloroplast development. They may function in photosynthetic capacity optimization by integrating responses to variable environmental and endogenous cues [ 1 , 2 , 3 , 4 , 5 , 6 ]. APRR2 interacts with calmodulin-like protein CML9 [ 7 ].
