Comments
Comment typeDescription
Catalytic ActivityATP + a protein = ADP + a phosphoprotein.
Disruption PhenotypeNo visible phenotype. Serk1 and serk2 double mutants are completely male sterile due to a failure in tapetum specification. {ECO:0000269|PubMed:16284305, ECO:0000269|PubMed:16284306}.
FunctionSerine/threonine-kinase involved in brassinosteroid- dependent and -independent signaling pathways. Acts redundantly with SERK1 as a control point for sporophytic development controlling male gametophyte production. {ECO:0000269|PubMed:18667726}.
PtmAutophosphorylated. {ECO:0000269|PubMed:19105183}.
SimilarityBelongs to the protein kinase superfamily. Ser/Thr protein kinase family. {ECO:0000255|PROSITE-ProRule:PRU00159}.
SimilarityContains 1 protein kinase domain. {ECO:0000255|PROSITE-ProRule:PRU00159}.
SimilarityContains 4 LRR (leucine-rich) repeats. {ECO:0000305}.
Subcellular LocationCell membrane {ECO:0000269|PubMed:16284305}; Single-pass type I membrane protein {ECO:0000269|PubMed:16284305}.
SubunitHomo- and heterodimer. Component of the SERK1 signaling complex, composed of KAPP, CDC48A, GRF6 or GRF7, SERK1, SERK2, SERK3/BAK1 and BRI1 (By similarity). Interacts with the EF-Tu receptor EFR and FLS2 in a specific ligand-induced manner. {ECO:0000250, ECO:0000269|PubMed:16284305, ECO:0000269|PubMed:21693696}.
Tissue SpecificityExpressed in flowers, tapetum, developing microspores, all cells of the embryo sac, provascular strands and developing vascular bundles. Low expression in adult vascular tissue. {ECO:0000269|PubMed:16284305}.
