TRIM72: Proteins and Enzymes

Muscle-specific protein that plays a central role in cell membrane repair by nucleating the assembly of therepair machinery at injury sites. Specifically binds phosphatidylserine. Acts as a sensor of oxidation: upon membranedamage, entry of extracellular oxidative environment results in disulfide bond formation and homooligomerization atthe injury site. This oligomerization acts as a nucleation site for recruitment of TRIM72-containing vesicles to theinjury site, leading to membrane patch formation. Probably acts upstream of the Ca(2+)-dependent membrane resealingprocess. Required for transport of DYSF to sites of cell injury during repair patch formation. Regulates membranebudding and exocytosis. May be involved in the regulation of the mobility of KCNB1-containing endocytic vesicles (Bysimilarity)
