PARTIAL PEPTIDE OF LACRITIN

摘要

Disclosed is a polypeptide comprising a partial sequence of lacritin, which can promote the adhesion between a cell and an extracellular matrix. Also disclosed is a polypeptide comprising a partial sequence of lacritin, which has a tear secretion-promoting activity. Specifically disclosed is a polypeptide which comprises the amino acid sequence depicted in SEQ ID NO:1 (which is a specific partial sequence of lacritin) and has an amino acid length of 70 resides or shorter. The polypeptide can promote the adhesion between a cell and an extracellular matrix. The polypeptide can also promote the tear secretion in a lacrimal glad acinar cell.
