    Summary
    Predicted to enable protein kinase A regulatory subunit binding activity. Involved in protein localization. Located in terminal bouton. Colocalizes with presynaptic membrane. Is expressed in several structures, including ectoderm; ectoderm anlage; extended germ band embryo; presumptive embryonic/larval digestive system; and stage 5 embryo. Human ortholog(s) of this gene implicated in Nance-Horan syndrome and cataract 40. Orthologous to human NHS (NHS actin remodeling regulator). [provided by Alliance of Genome Resources, Apr 2022]
