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]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    Description
    Transcript Variant: This variant (3) contains alternate 5' exon structure and it thus differs in the 5' UTR and 5' coding region, and it uses an alternate in-frame splice site in the 3' coding region, compared to variant 1. The encoded isoform (c) has a distinct N-terminus and is longer than isoform a. The exon combination of this variant is inferred based on partial transcript alignments.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (2, also known as ZO-1alpha-) lacks an alternate in-frame exon in the central coding region, compared to variant 1, resulting in an isoform (b) that is shorter than isoform a. Isoform b is found in both endothelial cells and the highly specialized epithelial junctions of renal glomeruli and sertoli cells of the seminiferous tubules. The exon combination of this variant is inferred based on partial transcript alignments and data in PMID:1590354.
