Lacritin is a 12.3 kDa glycoprotein encoded in humans by the LACRT gene. Lacritin is a secreted protein found in tears and saliva. Lacritin also promotes tear secretion and the proliferation and survival of epithelial cells. Lacritin is thus a prosecretory mitogen with cell survival activity.Most lacritin is produced by the lacrimal gland including the accessory lacrimal gland of Wolfring.
