Comments Information

    • Function

    • Apparent precursor of a secreted, cationic, proline- and cysteine-rich peptide that contains Cys-Pro-Xaa repeats. Unlike cryptdin, the proposed mature peptide region lacks the structural motif characteristic of defensins. It may have microbicidal activit.

    • Tissue specificity

    • Paneth cells of the small bowel.
