Immunohistochemical analysis of paraffin-embedded human pancreas tissue using Occludin Antibody (HY-P81155, 1/100). The section was pretreated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked with quick block buffer for 0.5 hours at room temperature, washed with PBS and PBST, and then incubated with the primary antibody overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry analysis of A549 cells labeling Occludin/OCLN with Occludin/OCLN Antibody (HY-P81155) at 1/100 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with quick block buffer for 10 minutes at room temperature. Cells were then incubated with Occludin/OCLN Antibody (HY-P81155) at 1/100 dilution in quick block buffer overnight at 4 ℃. AF488-conjugated Goat Anti-Rabbit IgG H&L(HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background
-
Function
May play a role in the formation and regulation of the tight junction (TJ) paracellular permeability barrier. It is able to induce adhesion when expressed in cells lacking tight junctions; (Microbial infection) Acts as a coreceptor for hepatitis C virus (HCV) in hepatocytes
-
Subcellular Localization
Cell membrane; Multi-pass membrane protein; Cell junction, tight junction
-
Expression
Tissue_specificity:It is located at the tight junctions of epithelial and endothelial cells. It is highly expressed in the kidneys. It was not detected in the testes. -

Q16625 has 7 isomers: Q16625-1: 59144 Da (predicted); Q16625-2: 52706 Da (predicted); Q16625-3: 54124 Da (predicted); Q16625-4: 31602 Da (predicted); Q16625-5: 23324 Da (predicted); Q16625-6: 8033 Da (predicted); Q16625-7: 8175 Da (predicted).
Dephosphorylated by PTPRJ. The tyrosine phosphorylation on Tyr-398 and Tyr-402 reduces its ability to interact with TJP1. Phosphorylation at Ser-490 also attenuates the interaction with TJP1;(Microbial infection) Cleaved by S.pyogenes SpeB protease; leading to its degradation (PubMed:23532847). Degradation by SpeB promotes bacterial translocation across the host epithelial barrier (PubMed:23532847) -
