Summary: Predicted to enable cell adhesion molecule binding activity. Acts upstream of or within regulation of G1/S transition of mitotic cell cycle. Located in several cellular components, including apical plasma membrane; bicellular tight junction; and cytosol. Is expressed in alimentary system epithelium and genitourinary system. Orthologous to human TJP3 (tight junction protein 3). [provided by Alliance of Genome Resources, Dec 2024]

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.
