Secreted effector that, with CRN63, is critical to pathogenesis by modulating host defenses (PubMed:21071601). Suppresses cell death elicited by the P.sojae necrosis-inducing protein or CRN63 (PubMed:21071601). CRN115 and CRN63 may share the same molecular host targets that are involved in the cell death signal transduction pathway and that their differential activities are dependent on plant nuclear localization or not (PubMed:21071601). Forms a homodimer via an inverted association manner (Probable). Forms a heteroodimer with CRN63 (PubMed:27243217). Expression is the highest at the mycelium stage. The CRN proteins have modular architectures that include a signal peptide, a conserved N-terminus, and highly diverse C-terminal domains. The conserved CRN N-terminus harbors a distinct LXLFLAK motif, which is followed by the conserved DWL domain. A highly conserved HVLVXXP motif marks the end of the CRN N-terminal domains and forms a junction where diverse C-terminal domains are fused. The conserved CRN N-terminus mediates the translocation into the plant host cells. The C-terminal effector region is sufficient for its activity within the host cell. The predicted NLS is not required for its function to suppress CRN63- or NIP-derived cell death. Leads to a reduction of virulence on soybean. Belongs to the Crinkler effector family.
