Protein existenceEvidence at protein level.

General annotation (Comments)

Catalytic activity

ATP + a protein = ADP + a phosphoprotein. UniProtKB Q9H4A3

Cofactor

Magnesium By similarity. UniProtKB Q9H4A3

Enzyme regulation

Activation requires autophosphorylation of Ser-308. Phosphorylation of Ser-304 also promotes increased activity By similarity. UniProtKB Q9JIH7

Tissue specificity

Expressed in brain, lung, kidney, liver and pancreas, and in fetal tissues including placenta, fetal brain, lung and kidney. Very low levels of expression were also detected in fetal heart, thymus, liver and spleen. Ref.1 Ref.3

Sequence similarities

Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. WNK subfamily.

Contains 1 protein kinase domain.

Caution

Cys-176 is present instead of the conserved Lys which is expected to be an active site residue. Lys-159 appears to fulfill the required catalytic function. UniProtKB Q9JIH7

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9BYP7-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q9BYP7-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1247-1247: G → GGGYFGLSFTCPSLKNPISKKSWTRKLKSWAYRLRQSTSFFKRSKVRQ
     1567-1567: D → GKSCLINELEN
