Background
Function：Core component of the complement C1 complex, a multiprotein complex that initiates the classical pathway of the complement system, a cascade of proteins that leads to phagocytosis and breakdown of pathogens and signaling that strengthens the adaptive immune system (PubMed:12847249, PubMed:19006321, PubMed:24626930, PubMed:29449492, PubMed:3258649, PubMed:34155115, PubMed:6249812, PubMed:6776418). The classical complement pathway is initiated by the C1Q subcomplex of the C1 complex, which specifically binds IgG or IgM immunoglobulins complexed with antigens, forming antigen-antibody complexes on the surface of pathogens: C1QA, together with C1QB and C1QC, specifically recognizes and binds the Fc regions of IgG or IgM via its C1q domain (PubMed:12847249, PubMed:19006321, PubMed:24626930, PubMed:29449492, PubMed:3258649, PubMed:6776418). Immunoglobulin-binding activates the proenzyme C1R, which cleaves C1S, initiating the proteolytic cascade of the complement system (PubMed:29449492). The C1Q subcomplex is activated by a hexamer of IgG complexed with antigens, while it is activated by a pentameric IgM (PubMed:19706439, PubMed:24626930, PubMed:29449492). The C1Q subcomplex also recognizes and binds phosphatidylserine exposed on the surface of cells undergoing programmed cell death, possibly promoting activation of the complement system (PubMed:18250442)
Subcellular Localization：Secreted; Cell surface
Subunit：Core component of the complement C1 complex, a calcium-dependent complex composed of 1 molecule of the C1Q subcomplex, 2 molecules of C1R and 2 molecules of C1S (PubMed:23650384, PubMed:29449492, PubMed:34155115, PubMed:6249812). The C1Q subcomplex is composed 18 subunits: 3 chains of C1QA, C1QB, and C1QC trimerize to form 6 collagen-like triple helices connected to six globular ligand-recognition modules (C1q domain) (PubMed:12960167, PubMed:18250442, PubMed:20548024, PubMed:29449492, PubMed:2988513, PubMed:6952210). Interacts with CR1 (via Sushi 24 and Sushi 25 domains) (PubMed:29563915, PubMed:9324355). Interacts (via C-terminus) with CD33; this interaction activates CD33 inhibitory motifs (PubMed:28325905)

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
