This domain family is found in eukaryotes, and is approximately 40 amino acids in length. The family is found in association with Pfam:PF00069. There is a single completely conserved residue F that may be functionally important. OSR1 is involved in the signalling cascade which activates Na/K/2Cl cotransporter during osmotic stress. This domain is the C terminal domain of OSR1 which recognises a motif (Arg-Phe-Xaa-Val) on the OSR1-activating protein WNK1.	Domain
