Summary:
Sox proteins all contain a single ~70 amino acid High Mobility Group (HMG) DNA-binding domain with strong homology to that of Sry, the mammalian testisdetermining factor. In Drosophila melanogaster, there are four closely related members of the B group, Dichaete (D), Sox Neuro (Sox N), Sox 21a, and Sox 21b that each exhibit ~90% sequence identity within the HMG domain.The previous study has shown that Dichaete plays a major role in embryonic nervous system development and is expressed in several clusters of neurons in the brain, including intermingled olfactory LNs and central-complex neurons strongly expressed in local interneuron of the olfactory system. However, little is known about the possible expression and functions of the related group B Sox genes in the larval and adult brain. In particular, it is unclear if Sox N may function along with Dichaete in controlling the development or physiology of the adult olfactory system. Our data suggests Sox N potential role in the elaboration of the olfactory circuit formation.
