    Summary
    Predicted to enable ubiquitin protein ligase activity and zinc ion binding activity. Involved in several processes, including long-term memory; positive regulation of neuromuscular synaptic transmission; and regulation of synapse organization. Located in cytoplasmic vesicle and plasma membrane. Is expressed in larval central nervous system and spermatozoon. Used to study brain disease. Orthologous to human MYCBP2 (MYC binding protein 2).

    3. Results indicate that the ability of faf, hiw or Rdl to modulate sleep and protect against cognitive impairments during waking is circuit dependent. Decreasing hiw and Rdl within the Mushroom Bodies protects against the negative effects of sleep deprivation as indicated by the absence of a subsequent homeostatic response, or deficits in short-term memory.
