TMEM74 Inhibitors

Transmembrane protein 74, abbreviated as TMEM74, is a protein that in humans is encoded by the TMEM74 gene. TMEM74 belongs to the extensive family of transmembrane proteins, which are characterized by their ability to span the lipid bilayer of cellular membranes. These proteins are integral components of the membrane and are critical for various cellular functions, including signaling, transport, and maintaining the structural integrity of the cell.

TMEM74 has been implicated in cellular processes such as autophagy, a mechanism by which cells degrade and recycle cytoplasmic components to maintain cellular homeostasis and respond to stress. It is believed to participate in the early stages of autophagosome formation, the organelles responsible for encapsulating the cellular material to be recycled. This role is vital for cellular health and survival, particularly under conditions of nutrient deprivation or metabolic stress.The protein's transmembrane domains suggest that TMEM74 may interact with other membrane proteins or lipids to form complexes. These complexes could be involved in signaling pathways that initiate and regulate autophagy or other cellular responses. The exact function of TMEM74, however, is still not fully understood, and research is ongoing to elucidate its role in cellular physiology and pathology.
