Claudin-7 in lateral membranes may exist in a nonpolymerized form and may play some different roles other than the formation of tight junctions strands, for example, in the formation of a pool of claudin proteins or in the reinforcement of cell adhesion.

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.
