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/
