[https://www.uniprot.org/uniprot/SPEC_STRP8 SPEC_STRP8] Superantigen that acts as a causative agent of the symptoms associated with scarlet fever (PubMed:1500157, PubMed:1987034, PubMed:9253413, PubMed:11163233). Has been associated with streptococcal toxic shock-like disease and may play a role in the early events of rheumatic fever (PubMed:1500157, PubMed:9253413, PubMed:11163233). Superantigens cross-link major histocompatibility complex (MHC) class II and T-cell receptor (TCR) molecules, resulting in an overstimulation of T-cells associated with a massive release of pyrogenic and inflammatory cytokines (PubMed:9253413, PubMed:11163233).<ref>PMID:11163233</ref> <ref>PMID:1500157</ref> <ref>PMID:1987034</ref> <ref>PMID:9253413</ref>
