Gene Information

human ... CLDN1(9076)

General description

Claudin-1 (CLDN1) membrane protein belongs to the claudin family. It comprises four membrane-spanning regions, N- and C-terminal cytoplasmic domains, and two extracellular loops. The CLDN1 gene is mapped to human chromosome 3q28. It is expressed in the kidney, testis, intestine, brain, and liver.

Immunogen

Synthetic peptide directed towards the C terminal region of human CLDN1

Biochem/physiol Actions

Claudin-1 (CLDN1) is a key component of the tight junctions that mediate epithelial barrier functions. CLDN1 is dichotomous as it is downregulated in breast, esophageal and prostate cancer. The gene is overexpressed in oral squamous cell cancer, colon, nasopharyngeal and ovarian tumors. It is implicated in neonatal sclerosing cholangitis (NISCH) syndrome. CLDN1 is involved in dengue (DENV) entry and acts as a co-receptor for hepatitis C virus (HCV) entry.

Sequence

Synthetic peptide located within the following region: GQALFTGWAAASLCLLGGALLCCSCPRKTTSYPTPRPYPKPAPSSGKDYV

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.
