Histatins are antimicrobial and antifungal proteins, and have been found to play a role in wound-closure. A significant source of histatins is found in the serous fluid secreted by Ebner's glands, salivary glands at the back of the tongue, and produced by Acinus cells. Here they offer some early defense against incoming microbes.
The three major histatins are 1, 3, and 5. Histatin 2 is a degradation product of histatin 1, and all other histatins are degradation products of histatin 3. Therefore there are only two genes, HTN1 and HTN3.
