26930581 CLCA2 links junctional adhesion molecule EVA1, to cytosolic signaling proteins that modulate proliferation and differentiation.
25557950 Variants in CLCA2 were associated with an ileal involvement phenotype of Crohn's disease.
25548429 CLCA2 expression is higher in squamous cell carcinoma of the lung compared with adenocarcinoma.
22990203 These results strongly suggest that CLCA2 is involved in the p53 tumor suppressor network and has a significant effect on cell migration and invasion.
22431922 the reduced expression of CLCA2 was frequently observed in various kinds of cancers including prostate cancer
21909135 hCLCA2 is required for epithelial differentiation, and its loss during tumor progression contributes to metastasis.
20438785 Observational study of gene-disease association and gene-gene interaction. (HuGE Navigator)
20406964 Observational study of gene-disease association. (HuGE Navigator)
19654313 hCLCA2 Is a p53-Inducible Inhibitor of Breast Cancer Cell Proliferation.
19423540 Observational study of gene-disease association. (HuGE Navigator)
18950845 Observational study of gene-disease association. (HuGE Navigator)
16873362 Mostly extracellular with only a single transmembrane segment, unlikely to form a channel.
16158324 human CLCA2 protein and mRNA expression are elevated during epithelial stratification, suggesting that this protein plays a role in the growth of multi-layered corneal epithelia during both natural development and tissue cultivation.
15707651 immunohistochemistry clearly demonstrated colocalisation between hCLCA2 and integrin beta4
12612194 Expression of hSK4 as well as hCACC-2 and hCACC-3 but not hCACC-1 was demonstrated by reverse transcriptase PCR on native nasal tissues.
10758170 HIV-1 gp120 from both CCR5- and CXCR4-tropic HIV-1 strains opens calcium-activated potassium (K(Ca)), chloride, and calcium-permeant nonselective cation channels in macrophages; these signals are mediated by CCR5 and CXCR4
