Swollen crypt-specific mucin-like glycoprotein designated as SC mucin. (a) Schematic structure of shorter variant and longer variant of the SC mucin proteins. The bars represent signal peptide domains (SigP), proline, threonine and serine-rich domains (PTS-rich), and chitin-binding domains (CBD). (b) Composition of monosaccharides liberated by acid hydrolysis of shorter variant and longer variant of the SC mucin proteins retrieved from SDS-PAGE gels (N = 3).
