Summary
Predicted to enable protein domain specific binding activity. Involved in negative regulation of gene expression and tight junction organization. Located in several cellular components, including apical plasma membrane; apicolateral plasma membrane; and bicellular tight junction. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in Crohn's disease and pseudo-TORCH syndrome 1. Orthologous to human OCLN (occludin). [provided by Alliance of Genome Resources, Apr 2022]

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.
