This domain is mostly found at the end of the beta propellers (Pfam:PF07494) in a family of two component regulators. However they are also found tandemly repeated in Swiss:Q891H4 without other signal conduction domains being present. It's named after the conserved tyrosines found in the alignment. The exact function is not known.	Domain
