Given the functional parallels within this protein family, it is plausible that ZNG1E, if it belongs to this family or shares functional motifs, contributes similarly to localized antimicrobial defense."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nMoreover, the overlapping yet distinct regional patterns of beta‐defensin expression suggest that these proteins work cooperatively, potentially fine-tuning the innate immune response in the urogenital system.
