[Term] id: PR:000050168 name: secretory dimeric IgA1 immunoglobulin complex (human) def: "A polymeric IgA1 immunoglobulin complex (human) that is a dimer of secretory IgA1 immunoglobulin complex." [PRO:ADD, PMID:16362985, GOC:add, ISBN:0781765196] comment: Category=organism-complex. Requested by=HIPC. Requested by=CL. Note that an IgA1 immunoglobulin complex has the function of antigen binding if a suitable antigen is available. Dimeric IgA1 is by far the most common form of polymeric IgA. In human, only the IgA1 isotype is capable of a dimeric form. synonym: "h(IgA1/secretory)dimeric" EXACT PRO-short-label [PRO:DAN] synonym: "secretory dimeric IgA1 antibody (human)" EXACT [PRO:ADD, GOC:add] synonym: "secretory dimeric IgA antibody (human)" BROAD [PRO:ADD, GOC:add] intersection_of: PR:000050165 ! polymeric IgA1 immunoglobulin complex (human) intersection_of: has_component PR:000050163 {cardinality="2"} ! monomeric IgA1 immunoglobulin complex (human) intersection_of: has_component PR:000050169 ! polymeric immunoglobulin receptor secretory component (human) intersection_of: has_component PR:P01591 ! immunoglobulin J chain (human) relationship: only_in_taxon NCBITaxon:9606 !
