Polymeric immunoglobulin receptor (PIGR)

Target (abbrv.) PIGR
Target (full name) Polymeric immunoglobulin receptor
Somalogic ID (Sequence ID) SL005797 (3216-2_2)
Entrez Gene Symbol PIGR
UniProt ID P01833
UniProt Comment
  • This receptor binds polymeric IgA and IgM at the basolateral surface of epithelial cells. The complex is then transported across the cell to be secreted at the apical surface. During this process a cleavage occurs that separates the extracellular (known as the secretory component) from the transmembrane segment.

All locus annotations are based on the sentinel SNP (rs35400166).
However, the sentinel SNP is not contained in SNiPA's database (1000 Genomes Project, phase 3 version 5, European population). Thus, no information about linked genes or further functional annotation is available.
