Protein

Leucine-rich repeat receptor-like serine/threonine/tyrosine-protein kinase SOBIR1

Gene

SOBIR1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Dual specificity kinase acting on both serine/threonine- and tyrosine-containing substrates. Promotes the activation of plant defense and cell death. Functions as an inhibitor/regulator of abscission, probably by regulating membrane trafficking during abscission.2 Publications

Catalytic activityi
