UniProtKB description:  Receptor with a serine/threonine-protein kinase activity (By similarity). Together with SKM1, LRR-rich receptor-like kinase (LRR-RLK) required for male fertility by the perception of CLE43 and CLE45 peptides and the transduction of their promoting action in pollen tubes, especially under relatively high temperature (at 30 degrees Celsius), thus conferring tolerance against high temperature probably through the maintenance of mitochondrial activity (PubMed:23910659). Seems to not be involved in the perception of CLE45 peptide in roots (PubMed:27354416). Together with RGI1, RGI2, RGI3, RGI4 and RGI5, acts as receptor of RGF1, a peptide hormone that maintains the postembryonic root stem cell niche by regulating the expression levels and patterns of the transcription factor PLETHORA (PLT) (PubMed:27229311, PubMed:27229312). Links RGF1 signal with its downstream components (PubMed:27229311).
