== Function ==

[https://www.uniprot.org/uniprot/HIP1_MYCTU HIP1_MYCTU] Serine protease that promotes tuberculosis (TB) pathogenesis by promoting the processing and the extracellular release of the M.tuberculosis (Mtb) heat-shock protein GroEL2 (PubMed:18172199, PubMed:24830429, PubMed:28346784). Hip1-dependent cleavage of multimeric GroEL2 results in release of cleaved monomeric GroEL2 into the extracellular milieu. Conversion of multimeric GroEL2 into monomeric GroEL2 is likely to be a mechanism for regulating GroEL2 functions during Mtb pathogenesis (PubMed:24830429). In vitro, exhibits proteolytic activity against synthetic peptides and the general protease substrate azocasein, and exhibits esterase activity against the ester substrate p-nitrophenylbutyrate (PubMed:24830429, PubMed:28346784).<ref>PMID:18172199</ref> <ref>PMID:24830429</ref> <ref>PMID:28346784</ref> Key immunomodulatory virulence factor, which promotes survival in host macrophages and modulates host immune responses (PubMed:18172199, PubMed:21947769, PubMed:24659689). Impacts host innate immune responses by preventing robust macrophage activation (PubMed:18172199, PubMed:21947769). Dampens macrophage pro-inflammatory responses by limiting toll-like receptor 2 (TLR2) activation. It also dampens TLR2-independent activation of the inflammasome and limits secretion of interleukin-18 (IL-18). May act by masking cell surface interactions between TLR2 agonists on Mtb and TLR2 on macrophages (PubMed:21947769). In addition, impacts host adaptive immune responses. It prevents robust maturation of infected dendritic cells (DCs), limits the secretion of key pro-inflammatory cytokines such as IL-12, impairs Ag presentation, and modulates the nature of Ag-specific T-cell responses (PubMed:24659689).<ref>PMID:18172199</ref> <ref>PMID:21947769</ref> <ref>PMID:24659689</ref>
