Histatin 1 (HTN1) is a histidine-rich phosphoprotein.HTN1 functions as an antimicrobial peptide with 38 amino acids. It is highly enriched in human saliva. HTN1 gene is located on human chromosome 4q13.3.
Immunogen
HTN1 (NP_002150.1, 1 a.a. ~ 57 a.a) full-length human protein.
Histatin 1 (HTN1) promotes migration of oral keratinocytes and fibroblasts in vitro. It also contributes to endothelial cell adhesion, migration and angiogenesis. HTN1 helps in oral wound healing. HTN1 is used as a marker for human lacrimal epithelium in accessory lacrimal gland (ALG) and cadaveric main lacrimal gland (MLG). HTN1 also has candidacidal activity and helps in mineralization by adsorbing to hydroxyapatite.

Histatin-1 expression in human lacrimal epithelium
The aims of this study were to determine if histatin-1 (H1) is present in normal human tears and whether tear levels of H1 varied between normal patients and those with aqueous deficient dry eye disease (ADDE). Patient samples were obtained

Wounds in the oral cavity heal much faster than skin lesions. Among other factors, saliva is generally assumed to be of relevance to this feature. Rodent saliva contains large amounts of growth factors such as epidermal growth factor (EGF) and
