UniProt functional annotation for Q9SR05 | ||
|
|
|
|
|
|
||
| UniProt code: Q9SR05. |
|
||
| Organism: | |
Arabidopsis thaliana (Mouse-ear cress). |
| Taxonomy: | |
Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis. |
|
||
|
||
| Function: | |
Receptor-like protein kinase that controls pollen tube behavior by directing rupture at proper timing to release the sperm cell. {ECO:0000269|PubMed:19646876}. |
|
||
| Catalytic activity: | |
Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl- [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA- COMP:11604, ChEBI:CHEBI:15378, ChEBI:CHEBI:29999, ChEBI:CHEBI:30616, ChEBI:CHEBI:83421, ChEBI:CHEBI:456216; EC=2.7.11.1; |
| Catalytic activity: | |
Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L- threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060, Rhea:RHEA-COMP:11605, ChEBI:CHEBI:15378, ChEBI:CHEBI:30013, ChEBI:CHEBI:30616, ChEBI:CHEBI:61977, ChEBI:CHEBI:456216; EC=2.7.11.1; |
| Subcellular location: | |
Cell membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. |
| Tissue specificity: | |
Expressed in pollen, but not in pistils or seedlings. {ECO:0000269|PubMed:19646876}. |
| Disruption phenotype: | |
No effect on male fertility and pollen germination, but siliques slightly shorter. Anx1 and anx2 double mutants show defects in male gametophytes due to premature pollen tube rupture. {ECO:0000269|PubMed:19646876}. |
| Miscellaneous: | |
Male paralog of FERONIA, a female factor expressed in synergid cells that controls pollen tube behavior. |
| Miscellaneous: | |
Named Anxur after the husband of the Etruscan goddess of fertility Feronia. |
| Similarity: | |
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. {ECO:0000255|PROSITE-ProRule:PRU00159}. |
