Summaries for CLDN17 Gene

Entrez Gene Summary for CLDN17 Gene

  • This gene encodes a member of the claudin family. Claudins are integral membrane proteins and components of tight junction strands. Tight junction strands serve as a physical barrier to prevent solutes and water from passing freely through the paracellular space between epithelial or endothelial cell sheets, and also play critical roles in maintaining cell polarity and signal transductions. This gene is intronless and is clustered with CLDN8 on chromosome 21q22.11. [provided by RefSeq, Jun 2010]

GeneCards Summary for CLDN17 Gene

CLDN17 (Claudin 17) is a Protein Coding gene. Among its related pathways are Blood-Brain Barrier and Immune Cell Transmigration: VCAM-1/CD106 Signaling Pathways and Blood-Brain Barrier Pathway: Anatomy. Gene Ontology (GO) annotations related to this gene include identical protein binding and structural molecule activity. An important paralog of this gene is CLDN8.

UniProtKB/Swiss-Prot for CLDN17 Gene

  • Channel-forming tight junction protein with selectivity for anions, including chloride and bicarbonate, and for solutes smaller than 9 Angstrom in diameter. In the kidney proximal tubule, may be involved in quantitative reabsorption of filtered anions. Does not affect water permeability.
