Grozdanovic, Čavić, Nešić, Andjelković, Akbari, Smit, Gavrović-Jankulović: Kiwifruit cysteine protease actinidin compromises the intestinal barrier by disrupting tight junctions. in Biochimica et biophysica acta 2016
PLD2 is pivotal in the regulation of the integrity of epithelial tight junctions and occludin turn over, thereby implicating it in the pathogenesis of colitis.
Adherens as well as tight junction marker proteins were rapidly and consistently upregulated in both the germinal as well as the functional layer of the oral mucosa. This represents a previously unknown parameter of the epithelial radiation response to clinically relevant fractionation protocols. CONCLUSION: Fractionated irradiation significantly enhanced the expression of all proteins investigated. This study revealed a
The C-terminal DSP domain induced phosphorylation of occludin Ser(490) and focal adhesion kinase (FAK) Ser(722) and Tyr(576). Coexpression of DSP, occludin and FAK was detected in dental mesenchymal cells during tooth development. Occludin physically interacts with FAK, and occludin and FAK phosphorylation can be blocked by DSP and occludin antibodies.

Low occludin expression is associated with Renal cell carcinoma.
decreased interaction between ZO-1 and occludin might contribute to the epiphora occurred in the transplanted submandibular glands
integration of claudin-2, occludin and ZO-1 is necessary for maintaining the function of the proximal tubular epithelium.
Molecular studies of the OCLN gene (NM_001205254) identified six distinct candidate mutations in polymicrogyria.

This gene encodes an integral membrane protein that is required for cytokine-induced regulation of the tight junction paracellular permeability barrier. Mutations in this gene are thought to be a cause of band-like calcification with simplified gyration and polymicrogyria (BLC-PMG), an autosomal recessive neurologic disorder that is also known as pseudo-TORCH syndrome. Alternative splicing results in multiple transcript variants. A related pseudogene is present 1.5 Mb downstream on the q arm of chromosome 5.
