OPTN seems to have an important role in bone metabolism by being part of NfkB pathway. CCDC3 is highly expressed in adipocytes and it seems to be negatively regulated by TNFa, however the mechanisms are not very clear. These genes have a ‘head-to-head’ orientation in the genome, which suggests that they might be regulated by a bidirectional promoter that coordinates the expression of both genes in different tissues. Using bioinformatic tools we analyzed the shared re...

Optineurin (OPTN) is a protein encoded by the OPTN gene. This protein is involved in several cellular mechanisms such as autophagy, NF-κB signaling, cellular morphogenesis, membrane and vesicle trafficking, and transcription activation. Mutations in OPTN have been described in glaucoma, amyotrophic lateral sclerosis and other neurological diseases. More recently, a polymorphism in this gene was also identified by a genome wide association study to be ass...
