    ana is expressed in four spots in the wing pouch and an additional spot in the notum.

    ana transcripts are expressed in scattered cells throughout the larval CNS. Based on the distribution, morphology and nonneural identity (as demonstrated by double labeling with a neuron-specific marker), these cells are identified as glia.

        Gene expression is increased in response to the presence of two copies of Scer\GAL4hs.PB.

        Shows particularly robust cycling of transcription in adult heads, as assessed by expression analysis using high density oligonucleotide arrays with probe generated during three 12-point time course experiments over the course of 6 days.

        ana encodes a secreted glial glycoprotein that represses neuroblast proliferation in the larval brain.

        trol acts downstream of ana, it is possible that trol may function to inactivate or bypass ana repression to activate cell proliferation.

        The ana locus controls the proliferation of neuroblasts, but is expressed in glia. In mutants, quiescent neuroblasts enter S phase precociously.

        Required for neuroblast proliferation but expressed in glial cells.
