Also known as: ZO-2
Summary: Predicted to enable several functions, including cell adhesion molecule binding activity; protein tyrosine kinase binding activity; and transmembrane transporter binding activity. Acts upstream of or within negative regulation of osteoclast development and negative regulation of tumor necrosis factor-mediated signaling pathway. Located in nucleus; plasma membrane; and tight junction. Is expressed in several structures, including early conceptus; genitourinary system; inner ear; neural ectoderm; and tooth. Human ortholog(s) of this gene implicated in disease of metabolism and progressive familial intrahepatic cholestasis 4. Orthologous to human TJP2 (tight junction protein 2).

Podocyte-specific deletion of the ZO-2 gene did not cause overt defects; however, double knockout of ZO-1 and ZO-2 genes accelerated the defects observed in ZO-1 knockout mice. These results suggest that ZO-2 plays supportive roles in the ZO-1-dependent regulation of podocyte filtration barrier.

In the present study, we found that the protein level of ZO-2, a scaffolding tight junction protein, decreased in the bladder of OVX mice indicating a possible role in overactive bladder.

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.
