PLEC encodes plectin, a cytoskeletal protein that maintains tissue integrity. GRINA encodes TMBIM3, which regulates cell survival. We hypothesized that in a joint predisposed to Osteoarthritis (OA), expression of these genes alters to combat aberrant biomechanics and is epigenetically regulated. However, carriage of the OA risk-conferring allele at this locus hinders this response and contributes to disease development.

The cytoplasmic N-terminal half of GRINA (which spans a Proline-rich domain) contains a potential DNA-binding sequence, in addition to cleavage target sites and probable PY-nuclear localization sequences, that may enable it to be released from the rest of the protein and enter the nucleus under suitable conditions, where it could participate in the transcription, alternative splicing, and mRNA export.

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.
