Arabidopsis	At3g25560	Receptor kinase acting, redundantly with other CIKs (e.g. CIK1, CIK2, CIK3, CIK5 and CIK6), as a coreceptor of CLV1, CLV2/CRN and RPK2, and required for CLAVATA-family peptides (e.g. CLV3, CLE25, CLE26 and CLE45) signaling through phosphorylation; this signaling regulates protophloem differentiation and the maintenance of shoot apical meristem (SAM) and root apical meristem (RAM) homeostasis, and acts down-stream of BRX and OPS.
