Verification Image

Western blot analysis of extracts from A431 (lane 2(20μg), A431 (lane 3(40μg), using Claudin 1 Antibody. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.

Background

Function：Claudins function as major constituents of the tight junction complexes that regulate the permeability of epithelia. While some claudin family members play essential roles in the formation of impermeable barriers, others mediate the permeability to ions and small molecules. Often, several claudin family members are coexpressed and interact with each other, and this determines the overall permeability. CLDN1 is required to prevent the paracellular diffusion of small molecules through tight junctions in the epidermis and is required for the normal barrier function of the skin. Required for normal water homeostasis and to prevent excessive water loss through the skin, probably via an indirect effect on the expression levels of other proteins, since CLDN1 itself seems to be dispensable for water barrier formation in keratinocyte tight junctions (PubMed:23407391); (Microbial infection) Acts as a co-receptor for hepatitis C virus (HCV) in hepatocytes (PubMed:17325668, PubMed:20375010, PubMed:24038151). Associates with CD81 and the CLDN1-CD81 receptor complex is essential for HCV entry into host cell (PubMed:20375010). Acts as a receptor for dengue virus (PubMed:24074594)

Subcellular Localization：Cell junction, tight junction; Cell membrane; Multi-pass membrane protein; Basolateral cell membrane

Expression：
Tissue_specificity:It is highly expressed in the liver and kidneys. It is also expressed in the heart, brain, spleen, lungs, and testes.
Positive sample: A431 cell lysate, HUVEC cell lysate, Caco-2 cell lysate, mouse skin tissue lysate, mouse liver tissue lysate, rat skin tissue lysate, rat liver tissue lysate, human esophageal can

Subunit：Homopolymers interact with CLDN3, but not CLDN2, homopolymers. Can form homo- and heteropolymers with other claudin family members (PubMed:23704991).
