Function
PROS_DROME Required for proper neuronal differentiation of most or all neurons and their precursors in central and peripheral nervous systems, axonal outgrowth and pathfinding. Not required for the specification of neuronal identity. May regulate transcription by binding to DNA.[1] [2] [3] [4]

Publication Abstract from PubMed
The Prospero transcription factor promotes neural differentiation in Drosophila, and its activity is tightly regulated by modulating its subcellular localization. Prospero is exported from the nucleus of neural precursors but imported into the nucleus of daughter cells, which is necessary for their proper differentiation. Prospero has a highly divergent putative homeodomain adjacent to a conserved Prospero domain; both are required for sequence-specific DNA binding. Here we show that the structure of these two regions consists of a single structural unit (a homeo-prospero domain), in which the Prospero domain region is in position to contribute to DNA binding and also to mask a defined nuclear export signal that is within the putative homeodomain region. We propose that the homeo-prospero domain coordinately regulates Prospero nuclear localization and DNA binding specificity.
