Disease relevance of PIGR

The polymeric immunoglobulin receptor-like milk protein inhibited HIV-1 reverse transcriptase (RT) with an IC(50) of 4.8 microM [1].
A polymeric immunoglobulin receptor-like milk protein with inhibitory activity on human immunodeficiency virus type 1 reverse transcriptase [1].

High impact information on PIGR

Although BFA has been thought to act only on biosynthetic organelles, we now show that this drug also reversibly blocks polymeric immunoglobulin receptor-mediated transcytosis in MDCK cells [2].
Adaptor binding was partially inhibited by soluble peptides representing the cytoplasmic domains of the asialoglycoprotein receptor and the polymeric immunoglobulin receptor [3].
Inasmuch as this mouse B cell pIgR binds IgM better than IgA, it is similar to human pIgR and differs from rat, mouse, and rabbit epithelial cell pIgRs that bind IgA but not IgM [4].
The polymeric immunoglobulin receptor (transmembrane secretory component) mediates transcellular transport of dimeric immunoglobulin A (IgA) and pentameric IgM in glandular and mucosal epithelial cells. cDNAs encoding two forms of the bovine polymeric immunoglobulin receptor (pIgR) have been cloned and sequenced [5].
Polymeric immunoglobulin receptor (PIGR) mediates transcellular transport of secretory antibodies in glandular and mucosal epithelial cells [6].

Biological context of PIGR

Using in situ hybridization, PIGR was localized to bovine chromosome 16, segment q13, thus confirming the recent assignment of syntenic group U1 to this chromosome [6].

Anatomical context of PIGR

By use of a bovine-rodent somatic cell hybrid panel the bovine PIGR locus has been assigned to syntenic group U1 [6].

Analytical, diagnostic and therapeutic context of PIGR

In Northern blot analysis of various bovine tissues, only the long form of pIgR mRNA was detected [5].
Direct PCR sequencing of a segment in the PIGR coding region (nucleotides 162-413) from 13 bulls of Norwegian Cattle revealed single nucleotide exchanges at two positions [6].
