Mouse PIR-B is a 125 kDa type I transmembrane glycoprotein with six Ig-like domains in its extracellular domain (ECD) and four ITIM-like sequences in its cytoplasmic domain. The ECD of PIR-B is highly homologous to the ECDs of multiple mouse PIR-A receptors (92‑99% amino acid sequence homology), which have short cytoplasmic tails lacking ITIM motifs. PIR-A receptors have a charged residue in their transmembrane domain that facilitates interaction with ITAM-containing adaptor molecules. Whereas PIR-A receptors deliver activation signals, PIR-B can inhibit receptor-mediated activation signaling. PIR-A and PIR-B have been shown to bind various mouse MHC class I molecules. They have been proposed to be orthologs of human leukocyte immunoglobulin-like receptors.

Detection of PIR-B by Immunohistochemistry
The effect of PirB knockdown in the retina by AAV PirB shRNA. A GFP (green, 488) expression in the retina transfected with AAV PirB shRNA or AAV shRNA for 21 days. red * represents the injection site, and the purple dotted line shows the area without the retinal tissue. Scale bars: 150 μm. B GFP staining in the PBS group. DAPI represents nuclear staining (blue fluorescence). Scale bar: 250 μm. C GFP (green, 488) and beta -Ш Tubulin (red, 594) fluorescent staining in the AAV PirB shRNA group. DAPI represents nuclear staining (blue). Scale bar: 250 μm. Small white arrows in c show GFP and beta -Ш Tubulin co-localization. D GFP (green, 488) and Vimentin (red, 594) fluorescent staining in the AAV PirB shRNA group. DAPI represents nuclear staining (blue). Scale bar: 250 μm. Small white arrows in d show GFP and Vimentin co-localization. E Bar charts showing PirB expression in the retina tissue. GAPDH was used as an internal reference. The ratios of gray values of target proteins to those of respective internal references are provided. The experiment was repeated three times (n = 4). Data represent the mean ± standard deviation. One-way ANOVA was performed, and Student’s t-test was used for group-pair comparisons used. **, p < 0.01 Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/34380548), licensed under a CC-BY license.
