Protein attributes

Sequence length	608 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in the innate immune MAP kinase signaling cascade (MEKK1, MKK4/MKK5 and MPK3/MPK6) downstream of bacterial flagellin receptor FLS2. May be involved in the cold and salinity stress-mediated MAP kinase signaling cascade (MEKK1, MEK1/MKK2 and MPK4/MPK6). Activates downstream MKK2, MKK4 and MKK5. Ref.8 Ref.10
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Subunit structure	Interacts with MEK1, MMK2 and MPK4. May form a ternary complex with MEK1 or MMK2 and MPK4. Ref.7
Induction	By touch, cold and salinity stress. Ref.1 Ref.6
Sequence similarities	Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily. Contains 1 protein kinase domain.
Sequence caution	The sequence AAA99196.1 differs from that shown. Reason: Frameshift at several positions. The sequence AAA99196.1 differs from that shown. Reason: Sequencing errors.
