  3. PR-5/Thaumatin-like Proteins Occur In Insects, Nematodes and Some Fungi • Sequence and structural similarity with plant PR-5 proteins • As families Functions defense against pathogen Innate Immunity conidial germination ?

  4. Are PR-5 Domains Equivalent To Mammalian gC1q Protein Domains? Innate/Adaptive immunity Energy metabolism Adiponectin Hibernation-specific proteins TNFalfa Complement C1q Brain-specific proteins Structural proteins Neurotransmitters? Collagen

  5. What Are Functions Of PR-5 Domain Proteins In Plants? Animals gC1q Plants PR-5 ? Energy Metabolism ↓ Carbon utilization Energy Metabolism Defense Defense
