The Drosophila CPEB protein Orb2 has a novel expression pattern and is important for asymmetric cell division and nervous system function.

Abstract excerpt

Cytoplasmic polyadenylation element binding (CPEB) proteins bind mRNAs to regulate their localization and translation. While the first CPEBs discovered were germline specific, subsequent studies indicate that CPEBs also function in many somatic tissues including the nervous system. Drosophila has two CPEB family members. One of these, orb, plays a key role in the establishment of polarity axes in the developing...
