UniProt annotation for Y1061_ARATH » Pollen receptor-like kinase 5
FUNCTION: Receptor-like kinase involved in the control of pollen germination and pollen tube polar growth (PubMed). The extracellular domain serves as a sensor for peptides derived from GRI (PubMed). May act as a downstream element for ROS- dependent cell death induced by GRI (PubMed).

CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein.

SUBUNIT: Interacts with the GRI peptide.

TISSUE SPECIFICITY: Expressed in pollen and/or in flowers (PubMed). Detected at low levels in leaves (PubMed).

INDUCTION: Up-regulated by biotic and abiotic stresses.

DOMAIN: The protein kinase domain may be catalytically impaired due to the lack of the conserved Asp active site at position 500, which is replaced by a His residue.
