Gene Group (FlyBase)
AXONEMAL INNER ARM DYNEIN HEAVY CHAINS -
Dynein heavy chains are minus end-directed microtubule motor proteins. Axonemal dynein complexes interact with adjacent microtubules in the axoneme. Coordinated binding and release of the axonemal dyneins slide the microtubules relative to each other causing the axoneme to bend driving ciliary and flagellar motion. Axonemal inner arm dynein heavy chains are the microtubule-binding motor protein of the dynein inner arm. (Adapted from FBrf0230280).

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Additional Descriptive Data

As part of a survey of ciliary motility gene homologs in Drosophila, expression of Dhc98D was assayed in motile ciliated cell types. Expression was observed in sperm (testis) but not chordotonal neurons.

Dhc98D transcripts are expressed in male testis and at lower levels in females and embryos.

        dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

        Spindle pole movements in embryos are directed by a temporally coordinated balance of forces generated by three mitotic motors; cytoplasmic dynein, Klp61F and ncd. Dynein acts to move the poles apart throughout mitosis, and this activity is augmented by Klp61F after the fenestration of the nuclear envelope, which occurs at the onset of prometaphase. ncd generates forces that pull the poles together between interphase and metaphase, antagonising the activity of both cytoplasmic dynein and Klp61F and serving as a brake for spindle assembly.

        Identification: PCR screen for Dynein heavy chain genes.

        Dhc98D has been cloned and characterised.
