May play a protective role in the innate immune response to parasite infection. Expressed in the globlet and Paneth cells of the small intestine of infected mice. Expressed in the ileum of uninfected mice. Up-regulated by infection with T.spiralis (at protein level). Also induced by infection with the helminth parasite N.brasiliensis. Constitutive expression does not lead to enhanced immunity to N.brasiliensis or M.tuberculosis.
