CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass type I
CC membrane protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Mostly expressed in developing organs, including
CC bud clusters, flowers, siliques and young rosettes. Also detected in
CC mature aboveground organs, such as leaves, stems and pedicels, but
CC barely in roots. {ECO:0000269|PubMed:14985254}.
CC -!- DEVELOPMENTAL STAGE: At the vegetative stage, strongly expressed in the
CC shoot meristem, leaf primordia and juvenile leaves. At the reproductive
CC stage, localized in the young developing flowers.
CC {ECO:0000269|PubMed:14985254}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. {ECO:0000255|PROSITE-ProRule:PRU00159}.
