NCBI Protein Information
GBF's pro-rich region-interacting factor 1
NCBI Summary
Encodes GLK1, Golden2-like 1, one of a pair of partially redundant nuclear transcription factors that regulate chloroplast development in a cell-autonomous manner. GLK2, Golden2-like 2, is encoded by At5g44190. GLK1 and GLK2 regulate the expression of the photosynthetic apparatus.

UniProt Comments
Transcriptional activator that functions with GLK2 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:17533111, PubMed:18643989, PubMed:19376934, PubMed:19383092, PubMed:19726569). Prevents premature senescence (PubMed:23459204).
