TMEM129 Inhibitors

MEM129 (Transmembrane Protein 129) is an E3 ubiquitin-protein ligase embedded within the cellular architecture as a type II transmembrane protein. It is significantly involved in the Endoplasmic Reticulum Associated Degradation (ERAD) pathway-a cellular quality control mechanism responsible for identifying and targeting misfolded proteins in the endoplasmic reticulum (ER) for proteasomal degradation. TMEM129 participates in this pathway by tagging defective proteins with ubiquitin molecules, a post-translational modification that marks them for removal by the proteasome, ensuring cellular homeostasis and proper protein function.

TMEM129's involvement in the ERAD pathway underscores its critical role in maintaining cellular integrity and functionality. Misfolded or improperly assembled proteins can disrupt cellular processes, lead to the aggregation of non-functional proteins, and induce cellular stress. By facilitating the degradation of such aberrant proteins, TMEM129 aids in preserving the balance and smooth operation of cellular protein machinery.In conclusion, TMEM129 is a crucial component of the cellular ubiquitination and degradation system, ensuring that proteins within the cell maintain their integrity, functionality, and proper conformation. Its role is pivotal in inhibiting the accumulation of misfolded proteins, thereby aiding in the maintenance of cellular health and the inhibition of protein aggregation-related stress and cellular dysfunctions.
