Synthesis pass · prose summary of the discoveries below

CD46 (membrane cofactor protein) is a ubiquitously expressed type I transmembrane glycoprotein that integrates innate complement regulation, pathogen entry, and adaptive T cell control (PMID:1910685, PMID:12540904). Its extracellular region is built from short consensus repeat (SCR) domains that serve as a cofactor for serine protease factor I, driving proteolytic inactivation of C3b and C4b deposited on host cell surfaces and thereby protecting cells from complement-mediated lysis; on cell surfaces CD46 is the principal cofactor for classical-pathway C4b cleavage and restricts alternative-pathway C3b deposition (PMID:1910685, PMID:12055245). The SCR3/SCR4 module carries the complement cofactor site, spatially distinct from the SCR1/SCR2 region that pathogens exploit (PMID:7534417). CD46 is a receptor or entry factor for a wide range of pathogens, with distinct SCR domains assigned to each: measles virus engages SCR1/SCR2 through its hemagglutinin (PMID:7534417, PMID:7745681), HHV-6 requires SCR2/SCR3 via the gQ1/gQ2 glycoproteins (PMID:12171934, PMID:24215487), adenovirus species B binds the CCP2/SCR2 domain through the fiber knob (PMID:15919905, PMID:17898059) whereas species D binds via the hexon capsid (PMID:33384338), pathogenic Neisseria pili bind CD46 (PMID:9379894), and bovine viral diarrhea virus and cytomegalovirus also use CD46 for entry (PMID:14747544, PMID:31221976); pathogen engagement frequently triggers CD46 downregulation or shedding, as seen with measles hemagglutinin-driven downregulation and pilus/PilT-mediated shedding (PMID:7732009, PMID:14597734). On T cells CD46 acts as a costimulatory molecule whose two mutually exclusive cytoplasmic tail isoforms, CYT-1 and CYT-2 generated by alternative splicing, drive divergent outcomes (PMID:1601037, PMID:7692239, PMID:12055630): CD3/CD46 co-engagement first promotes Th1 effector responses then switches CD4+ T cells to IL-10-producing regulatory (Tr1) cells (PMID:12540904, PMID:20694009), with CYT-1 linking through the GOPC scaffold to the VPS34/Beclin1 autophagy machinery (PMID:19837375) and CYT-2 being tyrosine-phosphorylated by Lck and coupling to the kinase SPAK and the ICER/CREM axis to drive the IL-10 switch (PMID:20694009, PMID:10657632). The Notch ligand Jagged1 is an endogenous physiological CD46 ligand required for proper Th1-to-Tr1 transition (PMID:23086448). CD46 function is further tuned by regulated processing—presenilin/γ-secretase cleaves the cytoplasmic tails, MMP-9 mediates ectodomain shedding, and TCR-induced O-glycosylation changes govern immune-synapse recruitment—linking these events to disease states including CD46 deficiency, multiple sclerosis, rheumatoid arthritis and SLE (PMID:20018629, PMID:29066539, PMID:28444759, PMID:23086448).

2005 The CCP2 (SCR2) domain of CD46 is critical for adenovirus serotype 35 (Ad35) and Ad11 binding; substitution of amino acids at positions 130-135 or 152-156 of CD46 completely abolishes Ad35 receptor function; Ad35 competes with measles virus for CD46 binding but not with complement C3b; N-glycosylations of CD46 do not critically contribute to Ad35 infection. Competition experiments with known CD46 ligands (MV, C3b), CD46 point mutants, antibody blocking, Ad35 fiber-containing vector infection assays Journal of virology High 15919905
2007 Four residues in the Ad35 fiber knob (Phe242, Arg279, Ser282, Glu302) are critical for CD46 binding; mutation of these residues ablates CD46 binding without affecting knob trimerization; the Ad35 knob binds three CD46 molecules with KD = 15.5 nM; crystal structure of Ad35 knob at 2-Å resolution modeled with existing Ad11-CD46 structure indicates one CD46 molecule binds between two knob monomers.

1995 CD46 downregulation is mediated specifically by interaction between the extracellular domains of CD46 and MV hemagglutinin, occurring on the same cell membrane and through cell-to-cell contact; CD46 downregulation was reversible, restricted to CD46 (not other surface markers), and not mediated through PKA or PKC-dependent pathways.

2000 The CD46 cytoplasmic domains are required for CD46-mediated enhancement of IFN-α/β production in mouse macrophages in response to measles virus; mouse macrophages expressing a tailless CD46 mutant lacking cytoplasmic domains showed much lower IFN-α/β and nitric oxide production and were highly susceptible to MV; IFN-α/β synergizes with IFN-γ to restrict viral replication.

2004 CD46 receptor density determines the threshold for measles virus-induced cell-cell fusion: virus entry increases progressively with CD46 density, but intercellular fusion is minimal at low densities and increases dramatically above a threshold density; tumor cells express high CD46 densities (above threshold) leading to extensive syncytia, while normal cells express low densities resulting in infection without significant fusion. Engineered cell lines expressing a range of CD46 densities, quantitative readout of viral gene expression via virally encoded soluble marker peptide, fusion assays at different CD46 receptor densities Cancer research High 15256464
1995 Measles virus hemagglutinin (MV-H), but not the fusion protein (MV-F), determines CD46-dependent fusion specificity: cells expressing HMV + FCDV fused CD46-dependently (like MV); cells expressing HCDV + FMV fused CD46-independently (like CDV); CD46 co-immunoprecipitated with HMV but not with FMV or CDV glycoproteins.

2016 CD46 costimulation of CD4+ T cells leads to downregulation of miR-150, which targets the glucose transporter 1 encoding transcript SLC2A1, connecting CD46 signaling to glucose uptake regulation; CD46 costimulation induces larger miRNA expression changes than CD28; autocrine CD46 signaling operates downstream of CD28; increased miR-150 in IL-10-secreting (switched) Th1 cells contributes to IL-10 production. miRNA expression profiling in CD46-costimulated CD4+ T cells, CD46 blockade, miR-150 knockdown, SLC2A1 target validation, cytokine measurement Journal of immunology Medium 26746193
2017 TCR/CD3 stimulation of CD4+ T cells induces a reduction in apparent molecular mass of CD46 dependent on O-glycosylation; CD3-stimulated changes in CD46 O-glycosylation status reduce CD46 processing and T cell signaling; CD46 is recruited to the immune synapse in a manner requiring its STP (serine-threonine-proline-rich) region; immune synapse recruitment of CD46 switches T cells from IFN-γ to IL-10 production; CD4+ T cells from MS patients show increased surface CD46 without the CD3-stimulated mass shift.

2016 CD46 is subject to alternative splicing regulation: CD46 cassette exons 7 and 8 (extracellular domain-encoding) use noncanonical base-pairing to U1 snRNA at their 5' splice sites; exon 13 (cytoplasmic tail CYT-1) inclusion is regulated by PTBP1 and TIAL1 as splicing factors, and SRSF1 represses exon 13 inclusion; nonsense-mediated mRNA decay and transcription speed further regulate CD46 mRNA isoforms; antisense oligonucleotides successfully manipulated CD46 exon 13 inclusion.

2014 HHV-6A gQ1 and gQ2 glycoproteins within the gH/gL/gQ1/gQ2 tetrameric complex are critical for CD46 binding: replacement of HHV-6A gQ1 or gQ2 with HHV-6B counterparts abolished CD46 binding, while replacement of gH or gL with HHV-6B molecules did not affect CD46 binding.
