Bilaterans share a common anterior-posterior (A-P) axis that is patterned by the Homeotic selector (Hox) genes. In Drosophila melanogaster, Hox gene expression in spatially restricted domains along the A-P axis of the embryo determines segmental identity. Identifying the genetic mechanisms of HOX control of development is essential for understanding body patterning in animals. I identified and characterized the role of evolutionarily conserved protein domains of the HOX protein, Sex combs reduced (SCR), in protein function. SCR is required for establishing the identity of both the labial and prothoracic segments. To identify regions of functional importance, 15 Scr …
