[[http://www.uniprot.org/uniprot/CHLH_ARATH CHLH_ARATH]] Multifunctional protein involved in chlorophyll synthesis, plastid-to-nucleus retrograde signaling and abscisic acid (ABA) perception. In chlorophyll synthesis, catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX. The reaction takes place in two steps, with an ATP-dependent activation followed by an ATP-dependent chelation step. In addition to its function in the Mg-chelatase enzyme, is required for the plastid-to-nucleus retrograde signaling. The plastid-to-nucleus signal plays an important role in the coordinated expression of both nuclear- and chloroplast-localized genes that encode photosynthesis-related proteins. Has a role in mediating ABA signaling in stomatal guard cells and during seed germination. Binds ABA and is a positive regulator of ABA signaling.<ref>PMID:11172074</ref> <ref>PMID:17051210</ref> <ref>PMID:19363094</ref> <ref>PMID:19535472</ref> <ref>PMID:20543028</ref> <ref>PMID:21562844</ref> <ref>PMID:23011401</ref>
