TMEM155 Activators

TMEM155, formally recognized as Transmembrane Protein 155, is a protein encoded by the TMEM155 gene situated on human chromosome 4. Preliminary investigations have identified its predominant expression in the brain, placenta, and lymph nodes, hinting at its potential significance within these tissues 1. This protein's specific role and structure remain enigmatic, although its expression patterns have been explored in relation to various pathologies 2. TMEM155 has been shown to be activated by diacylglycerol (DAG) in a manner that is independent of protein kinase C and directly by inositol 1,4,5-triphosphate receptors (ITPR) with attached IP3. This activation suggests that the protein can respond to internal calcium store depletion 3. Delving into the molecular intricacies of TMEM155, it's discerned that this protein is interconnected with a series of predicted functional collaborators. Notably, it is linked with EXOSC9, which is an integral part of the RNA exosome complex. Another intriguing connection is with TRPC3, a transient receptor potential channel. These associations propose a possible engagement of TMEM155 in RNA processing and the calcium signaling pathway 4. Given the inherent complexity and the potential multi-faceted role of TMEM155, any activators targeting it would aim to augment its activity or expression. These activators might influence TMEM155 either through direct interaction or by modulating the pathways associated with it. While these insights provide a foundational understanding, the precise pathways, interactions, and broader roles of TMEM155 in cellular processes necessitate more exhaustive research endeavors.
