CC -!- FUNCTION: [Polymeric immunoglobulin receptor]: Mediates selective
CC transcytosis of polymeric IgA and IgM across mucosal epithelial cells.
CC Binds polymeric IgA and IgM at the basolateral surface of epithelial
CC cells. The complex is then transported across the cell to be secreted
CC at the apical surface. During this process, a cleavage occurs that
CC separates the extracellular (known as the secretory component) from the
CC transmembrane segment. {ECO:0000250|UniProtKB:P01833}.
CC -!- FUNCTION: [Secretory component]: Through its N-linked glycans ensures
CC anchoring of secretory IgA (sIgA) molecules to mucus lining the
CC epithelial surface to neutralize extracellular pathogens. On its own
CC (free form) may act as a non-specific microbial scavenger to prevent
CC pathogen interaction with epithelial cells.
CC {ECO:0000250|UniProtKB:P01833}.
CC -!- SUBUNIT: Interacts (mainly via CDR1-like domain) with dimeric IgA.
CC Interacts (mainly via CDR2-like domain) with pentameric IgM.
CC {ECO:0000250|UniProtKB:P01833}.
CC -!- SUBUNIT: [Secretory component]: Either free or part of the secretory
CC IgA (sIgA) complex that consists of two, four or five IgA monomers, and
CC two additional non-Ig polypeptides, namely the JCHAIN and the secretory
CC component (the proteolytic product of PIGR). Free secretory component
CC interacts with bacterial antigens toxA of C. difficile and eae of E.
CC coli. {ECO:0000250|UniProtKB:P01833}.
CC -!- SUBCELLULAR LOCATION: [Polymeric immunoglobulin receptor]: Cell
CC membrane {ECO:0000250|UniProtKB:P01833}; Single-pass type I membrane
CC protein {ECO:0000255}.
CC -!- SUBCELLULAR LOCATION: [Secretory component]: Secreted
CC {ECO:0000250|UniProtKB:P01833}.
CC -!- DOMAIN: The Ig-like V-type 1/D1 domain contains three complementarity
CC determining region-like loops CDR1-3, which mediate interaction with
CC IgA and IgM. {ECO:0000250|UniProtKB:P01833}.
CC -!- PTM: N-glycosylated. N-glycosylation is required for anchoring IgA
CC molecules to mucus, but is not necessary for Ig binding.
CC {ECO:0000250|UniProtKB:P01833}.
