Function

function

Transcriptional activator that functions with GLK1 to promote chloroplast development. Acts as an activator of nuclear photosynthetic genes involved in chlorophyll biosynthesis, light harvesting, and electron transport. Acts in a cell-autonomous manner to coordinate and maintain the photosynthetic apparatus within individual cells. May function in photosynthetic capacity optimization by integrating responses to variable environmental and endogenous cues (PubMed:11828027, PubMed:12220263, PubMed:18643989, PubMed:19376934, PubMed:19383092, PubMed:19726569).
Prevents premature senescence (PubMed:23459204).

Miscellaneous

Plants overexpressing GLK2 have a delay in flowering under long days.
