CC   -!- FUNCTION: Contributes to pathogen-associated molecular pattern (PAMP)-
CC       triggered immunity (PTI) signaling, including calcium signaling and
CC       root growth inhibition, and defense responses downstream of FLS2
CC       (PubMed:20413097, PubMed:25522736). Acts additively with BIK1 in PTI
CC       defenses (PubMed:20413097, PubMed:25522736). Seems not required for
CC       flg22-induced MAPK activation (Probable). Required for Pep1-induced
CC       defenses (PubMed:25522736). Pep1 is an endogenous elicitor that
CC       potentiates PAMP-inducible plant responses (PubMed:23431184,
CC       PubMed:25522736). {ECO:0000269|PubMed:20413097,

CC       ECO:0000269|PubMed:23431184}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:25522736};
CC       Lipid-anchor {ECO:0000269|PubMed:25522736}. Note=Myristoylation and
CC       proper targeting to plasma membrane is essential for signaling function
CC       in response to pathogen-associated molecular pattern (PAMP) such as
CC       flg22. {ECO:0000269|PubMed:25522736}.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative splicing; Named isoforms=1;
CC         Comment=A number of isoforms are produced. According to EST
CC         sequences.;
CC       Name=1;
CC         IsoId=Q8H186-1; Sequence=Displayed;
CC   -!- INDUCTION: Induced by flagellin (flg22). {ECO:0000269|PubMed:20413097}.
CC   -!- PTM: Phosphorylated upon flagellin (flg22) treatment.
CC       {ECO:0000269|PubMed:20404519, ECO:0000269|PubMed:20413097,
CC       ECO:0000269|PubMed:25522736}.
CC   -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC       conditions (PubMed:20413097). Abrogated kinase activity
CC       (PubMed:25522736). In cce5-2 and cce5-4, reduced calcium levels after
CC       elicitation with peptides representing bacteria-derived microbe- and
CC       damage-associated molecular patterns (MAMPs, flg22 and elf18, and the
CC       endogenous DAMP AtPep1), but normal response to chitin octamers.
CC       Reduced root growth inhibition response to flg22 (PubMed:25522736).
CC       {ECO:0000269|PubMed:20413097, ECO:0000269|PubMed:25522736}.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC       kinase family. {ECO:0000255|PROSITE-ProRule:PRU00159}.
