Indian hedgehog homolog (Drosophila), also known as IHH, is a protein which in humans is encoded by the IHH gene. This cell signaling protein is in the hedgehog signaling pathway. The several mammalian variants of the Drosophila hedgehog gene (which was the first named) have been named after the various species of hedgehog; the Indian hedgehog is honored by this one. The gene is not specific to Indian hedgehogs.
