B3GAT2 and bacterial infectious disease: Among this group of genes, the negative regulator Twin of M4 or Barbu showed the highest level of expression followed by a putative CCAT-binding transcription factor, the gene Enhancer of split mgamma, a basic Helix-Loop-Helix transcription factor related to Myc, Brother of Bearded A, which has been previously implicated in the fly immune response against bacterial infection [34], Amalgam, which codes for an Ig-like C2-type domain-containing protein involved in antigen binding and cell adhesion [35], and the putative enzyme CG31002 that possesses glucuronosyltransferase activity.
