  • CAP domain (IPR014044)
    • Pathogenesis-related protein 1-like, SCP domain (IPR034111)


This SCP-like extracellular protein domain is found in pathogenesis-related proteins from plants [PMID: 9880788]. Pathogenesis-related protein 1 (PR-1) accumulates after infection with pathogens, and may act as an anti-fungal agent or be involved in cell wall loosening [PMID: 7784503].

The SCP domain is also known as CAP domain [PMID: 18824526]. The wider family of SCP containing proteins includes plant pathogenesis-related protein 1 (PR-1), CRISPs, mammalian cysteine-rich secretory proteins, which combine SCP with a C-terminal cysteine rich domain, and allergen 5 from vespid venom. It has been proposed that SCP domains may function as endopeptidases.
