Summary: Predicted to enable identical protein binding activity and virus receptor activity. Involved in several processes, including cellular response to butyrate; cellular response to cytokine stimulus; and endothelial cell development. Located in apical plasma membrane; bicellular tight junction; and lateral plasma membrane. Biomarker of diabetic retinopathy; liver disease (multiple); and periodontitis.

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.
