    The protein

    Catalyzed reaction/ biological activity

  • required for folding of the secreted protein [protein|6EA4D86FA1EA6388054A4D863EB576187CD5AEEE|YqxI] [Pubmed|23937099]
  • Acts on substrates that are at least partially unfolded. The cleavage site P1 residue is normally between a pair of hydrophobic residues, such as Val-|-Val (according to UniProt)

    • Protein family

  • Peptidase S1C family (with [protein|796216BE9CD6DADFEADC29497253C81BF496A2ED|HtrB] and [protein|75B8C37E589C855D2BAD7FB51B9600E161ACFBD3|HtrC], according to UniProt)

    • Paralogous protein(s)

  • [protein|75B8C37E589C855D2BAD7FB51B9600E161ACFBD3|HtrC]

    • [SW|Domains]

  • cytoplasmic domain (aa 1 - 44) (according to UniProt)
  • transmembrane helix (aa 45 - 67) (according to UniProt)
  • extracellular domain (aa 68 - 479) (according to UniProt)
  • [SW|PDZ domain] (aa 342 - 441) (according to UniProt)

    • Structure

  • [PDB|3QO6] (from Arabidopsis thaliana, 37% identity) [pubmed|21532594]

    • [SW|Localization]

  • cell membrane (according to Swiss-Prot)
  • extracellular (signal peptide) [Pubmed|18957862]
  • randomly distributed in foci throughout the cell surface [Pubmed|22307758]
