Arabidopsis	At4g32250	Serine/threonine protein kinase acting as a regulatory component of the plastid protein import machinery by phosphorylating import receptors (e.g. the A-domain of TOC159, TOC120 and TOC132).	The novel chloroplast outer membrane kinase KOC1 is a required component of the plastid protein import machinery.; 2017; DOI: 10.1074/jbc.m117.776468; PMID: 28283569; https://pubmed.ncbi.nlm.nih.gov/28283569/
Arabidopsis	At5g13530	Mediates E2-dependent protein ubiquitination.	Powdery mildew resistance conferred by loss of the ENHANCED DISEASE RESISTANCE1 protein kinase is suppressed by a missense mutation in KEEP ON GOING, a regulator of abscisic acid signaling.; 2008; DOI: 10.1104/pp.108.127605; PMID: 18815384; https://pubmed.ncbi.nlm.nih.gov/18815384/
Arabidopsis	At2g17700	Serine/threonine protein kinase that specifically phosphorylates chloroplast precursor proteins in the cytosol within the cleavable presequences (transit peptides).
