Claudin 1 (CLDN1) Antibody (Loop1) Blocking peptide

Synthetic peptide

Product Information
Primary Accession O95832
Clone Names 70829102
Peptide ID 70829102
Additional Information
Gene ID 9076
Other Names Claudin-1, Senescence-associated epithelial membrane protein, CLDN1, CLD1, SEMP1
Target/Specificity The synthetic peptide sequence used to generate the antibody AP6308a was selected from the Loop1 region of human CLDN1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
Format The synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml deionized water for a final concentration of 1 mg/ml.
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.
PrecautionsThis product is for research use only. Not for use in diagnostic or therapeutic procedures.
Protein Information
Name CLDN1
Synonyms CLD1, SEMP1
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). CLDN1 acts as a coreceptor for HCV entry into hepatic cells.
Cellular Location Cell junction, tight junction. Cell membrane; Multi-pass membrane protein
Tissue Location Strongly expressed in liver and kidney. Expressed in heart, brain, spleen, lung and testis

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. CLDN1, 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.
