Protein architecture of bovine secreted mucins. Protein architecture of the human (Hs) and bovine (Bt) secreted mucins MUC2, MUC5AC, MUC5B, MUC6, MUC7 and MUC19. MUC5AC, MUC5B and MUC19 are presented as a shortened sequence, indicated by //. Domains detected by SMART  are SP: signal peptide, VWD: Von Willebrand Factor D; C8: domain with 8 conserved Cys residues; TIL: domain typically containing 10 Cys residues; VWC: Von Willebrand Factor C; PTS: Pro, Thr and Ser rich region; CT: C-terminal cystine knot-like domain.
