Related Product Information for anti-CLDN1 antibody

The gene encoding claudin-1 (CLDN1) has been mapped to human chromosome 3. The claudin-1 gene (CLDN1) is a member of a family of genes that encodes proteins found in tight junctions and it has been implicated as one of several receptors for late stage binding of hepatitis C virus (HCV). Claudin-1 is a recently discovered co-receptor for hepatitis C virus (HCV) that is required for late-stage binding of the virus. Because variants in the gene that encodes claudin-1 (CLDN1) could play a role in HCV infection, the genetic variants in regulatory regions of CLDN1 may alter susceptibility to HCV infection. Claudin1 (CLDN1) plays an important role not only in the intercellular barrier function of tight junctions (TJs) but also in migration and invasiveness of cancer cells. Previous cDNA microarrays indicated that CLDN1 (claudin-1) is an important gene for ovarian cancer-initiating cell (OCIC) invasion and adhesion. Tight junction protein claudin-1 (CLDN1) is mainly involved in the intercellular barrier function of epithelial cells and is known to be dysregulated in many cancer types, including gastrointestinal cancers. CLDN1 (claudin1) is essential for intercellular junctions and has been reported to be involving in cell migration and metastasis, making it as an oncogene in various cancer types. The miR-29a may regulate tumor growth and migration by targeting CLDN1, providing promising therapeutic targets for HCC.

NCBI Description

Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. These junctions are comprised of sets of continuous networking strands in the outwardly facing cytoplasmic leaflet, with complementary grooves in the inwardly facing extracytoplasmic leaflet. The protein encoded by this gene, a member of the claudin family, is an integral membrane protein and a component of tight junction strands. Loss of function mutations result in neonatal ichthyosis-sclerosing cholangitis syndrome. [provided by RefSeq, Jul 2008]

Uniprot Description

Claudin-1: Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium- independent cell-adhesion activity. Acts as a co- receptor for HCV entry into hepatic cells. Can form homo- and heteropolymers with other CLDN. Homopolymers interact with CLDN3, but not CLDN2, homopolymers. Directly interacts with TJP1/ZO-1, TJP2/ZO-2 and TJP3/ZO-3. Interacts with MPDZ and INADL. May interact with HCV E1 and E2 proteins. Strongly expressed in liver and kidney. Expressed in heart, brain, spleen, lung and testis. Belongs to the claudin family.
