Protein deltex-1 is a protein that in humans is encoded by the DTX1 gene.
Studies in Drosophila have identified this gene as encoding a positive regulator of the Notch-signaling pathway. The human gene encodes a protein of unknown function; however, it may play a role in basic helix-loop-helix transcription factor activity. Storage: Store at -20 °C for one year. Avoid repeated freeze/thaw cycles.
