UniProt annotation for RLK_ARATH » Pollen receptor-like kinase 1
FUNCTION: Receptor-like kinase involved in the control of pollen germination and pollen tube polar growth (PubMed).

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

SUBUNIT: Interacts in vitro with ROPGEF1 (via PRONE domain).

TISSUE SPECIFICITY: Expressed in pollen and/or in flowers, but not in leaves.

DOMAIN: The protein kinase domain may be catalytically impaired due to the lack of the conserved Asp active site at position 485, which is replaced by a His residue.
