A recent study on nature communication has determined the role of cytoglobin (cygb2) in regulating ciliary motility.

Cygb is a heme-containing globin protein, and unlike its pentacoordinate relatives myoglobin and hemoglobin, it is not involved in oxygen transport or storage. However, Cygb contains a hexacoordinate heme moiety expressed at low concentrations.
