Function

Cell surface protein involved in the host-parasite interaction during candidal infection. With MP65, represents a major component of the biofilm matrix. As a surface protein, binds the two human complement regulators CFH and CFHR1, as well as plasminogen PLG, mediates complement evasion and extra-cellular matrix interaction and/or degradation.

Protein Biology

Function

Cell surface protein involved in the host-parasite interaction during candidal infection (PubMed:17277107, PubMed:19850343, PubMed:20504767, PubMed:20644161, PubMed:21212281, PubMed:21245270, PubMed:21820180, PubMed:22074954, PubMed:22761575, PubMed:22844116, PubMed:9440517). With MP65, represents a major component of the biofilm matrix (PubMed:17277107). As a surface protein, binds the two human complement regulators CFH and CFHR1, as well as plasminogen PLG, mediates complement evasion and extra-cellular matrix interaction and/or degradation (PubMed:19850343, PubMed:20504767). As a released protein, enhances complement control in direct vicinity of the yeast and thus generates an additional protective layer which controls host complement attack, assisting the fungus in escaping host surveillance (PubMed:17277107, PubMed:19850343). Binds to host fluid-phase C3 and blocks cleavage of C3 to C3a and C3b, leading to inhibition of complement activation and protection from uptake of C.albicans by human macrophages (PubMed:20644161). Also mediates human complement control and complement evasion through binding to C4BPA, another human complement inhibitor, as well as through binding to host integrin alpha-M/beta-2 (PubMed:21212281, PubMed:21245270, PubMed:21820180, PubMed:22844116). Binds zinc from its environment and then reassociates with ZRT1 to acquire this essential metal (PubMed:22761575)

Subunit

Component of a multiprotein complex of 250 kDa composed of at least HYR1, MP65, and PRA1 (PubMed:17277107). Interacts with host Integrin alpha-M/beta-2 heterodimer (PubMed:17277107). Also binds human factor H (CFH), CFHR1, plasminogen (PLG), complement C3, and C4BPA (PubMed:19850343, PubMed:20644161, PubMed:21212281, PubMed:21245270). Interacts with ZRT101 (PubMed:22761575)
