“…Mammalian MAMs are formed by protein tethers, similar to the tetrameric tethering complexes in fungi known as ER-mitochondria encounter structures (ERMES) (Kornmann et al, 2009). However, of the more than 30 proteins involved in vertebrate MAM function, only two of them, GRAMD1A, which corresponds to yeast Lam6p, and MIRO (also known as RHOT1), which corresponds to yeast Gem1p, are conserved in ERMES (Kornmann et al, 2011;Elbaz-Alon et al, 2015). This increased complexity of animal MAMs suggests they acquired new roles beyond those controlled by ERMES (HerreraCruz and Simmen, 2017).…”
