NCBI Protein Information
GOLDEN2-like 2
NCBI Summary
Encodes GLK2, Golden2-like 2, one of a pair of partially redundant nuclear transcription factors that regulate chloroplast development in a cell-autonomous manner. GLK1, Golden2-like 1, is encoded by At2g20570. GLK1 and GLK2 regulate the expression of the photosynthetic apparatus.

UniProt Comments
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).
