Gene Gene information from NCBI Gene database.
Entrez ID 5284
Gene name Polymeric immunoglobulin receptor
Gene symbol PIGR
Synonyms (NCBI Gene)
-
Chromosome 1
Chromosome location 1q32.1
Summary This gene is a member of the immunoglobulin superfamily. The encoded poly-Ig receptor binds polymeric immunoglobulin molecules at the basolateral surface of epithelial cells; the complex is then transported across the cell to be secreted at the apical sur
