Plays a role in axonemal structure organization and motility. May be involved in axonemal pre-assembly of inner and outer dynein arms (IDA and ODA, respectively) for proper axoneme building for cilia motility. Localizes mainly to the cytoplasm. Present in the cell bodies of Ch neurons. Present at low level in the cilium. Specifically expressed in cells with flagella and motile cilia: chordotonal sensory neurons and sperm. During embryogenesis expression is restricted to developing Ch neurons and absent from other ciliated sensory neurons. In the pupal antenna, expressed exclusively in the Ch neurons of Johnston's organ. Expression is dependent on the transcription factors that regulate motile cilia such as Rfx and Fd3F. Sensory defects and loss of the axonemal dynein arms. Flies display defective proprioception as a result of malfunctioning Ch neurons caused by inner and outer dynein arms (IDA and ODA, respectively) defects. Males sterility due to immotile sperm. Belongs to the ZMYND10 family.
