    Other Comments

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

    dsRNA made from templates generated with primers directed against this gene is tested in an RNAi screen for effects on actin-based lamella formation.

    dock facilitates synapse formation by the RP3 motoneuron and is required for guidance of some interneuronal axons. dock mediated signalling may be important in remodelling the RP3 growth cone's cytoskelton.

    Loss of zygotic dock function causes a selective delay in synapse formation by the RP3 motoneuron at the cleft between muscles 7 and 6. In late stage 16 mutant embryos these muscles often lack innervation. By the third larval instar muscles have become innervated by RP3. dock mutants also show subtle defects in the CNS longitudinal axon pathway.

    dock can couple signals in either an SH2-dependent or an SH2-independent fashion in photoreceptor growth cones. dock displays different domain requirements in different neurons.

    Isolated in a yeast two-hybrid system, by screening for Ptp61F-interacting proteins.

    Mutations in dock disrupt photoreceptor cell axon guidance and targeting. Genetic mosaic analysis and cell-type-specific expression of dock transgenes demonstrate dock is required in receptor cells for proper innervation.

    Origin and Etymology
    Discoverer
    Etymology

    The gene is named "dreadlocks" for the appearance of the receptor cell projection pattern in the mutant.
