2.A.1.1.25
Myoinositol:H+ symporter, HMIT (also transport other inositols including scyllo-, muco- and chiro-, but not allo-inositol) (Aouameur et al., 2007). Expressed in the Golgi of the hippocampus and cortex. May also transport inositoltriphosphate (Di Daniel et al., 2009). Interacts directly with γ-secretase (9.B.47.1.1) to regulate its activity and the production of Abeta production, important in Alzheimer's disease (Teranishi et al. 2015).

Species:Homo sapiens [9606]
Number of TMSs:12
Location1 / Topology2 / Orientation3: Membrane1 / Multi-pass membrane protein2
