Tuftelin

 ( Teeth ) 

Tuftelin is an acidic Phosphorylation glycoprotein found in tooth enamel. In humans, the tuftelin protein is encoded by the TUFT1 gene. It is an acidic protein that is thought to play a role in dental enamel mineralization and is implicated in caries susceptibility. It is also thought to be involved with adaptation to hypoxia, mesenchymal stem cell function, and neurotrophin nerve growth factor mediated neuronal differentiation.

Classification There are two kinds of enamel proteins: Amelogenin and nonamelogenins. Tuftelin falls under nonamelogenins.

Function This protein is formed for a short time during amelogenesis. The function of tuftelins is under contention, but it is proposed that it acts to start the mineralization process of enamel during tooth development.

Other significant proteins in enamel are , , and .

Research The human encoding gene for tuftelin (TUFT1) was cloned by Profs. Danny Deutsch and Aharon Palmon from the Hebrew University-Hadassah School of Dental Medicine in Jerusalem.

Interactions

Tuftelin has been shown to interact with TFIP11.
