TJP1 - tight junction protein 1 Gene
Also Known as ZO-1
Species: Homo sapiens
About TJP1
This gene has 12 transcripts (splice variants), 1 gene allele, 288 orthologues and 3 paralogues. Ubiquitous expression in testis (RPKM 23.9), placenta (RPKM 23.2) and 24 other tissues.
Summary
This gene encodes a member of the membrane-associated guanylate kinase (MAGUK) family of proteins, and acts as a tight junction adaptor protein that also regulates adherens junctions. Tight junctions regulate the movement of ions and macromolecules between endothelial and epithelial cells. The multidomain structure of this scaffold protein, including a postsynaptic density 95/disc-large/zona occludens (PDZ) domain, a Src homology (SH3) domain, a guanylate kinase (GuK) domain and unique (U) motifs all help to co-ordinate binding of transmembrane proteins, cytosolic proteins, and F-actin, which are required for tight junction function. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2017]
