Background: TMEM41B

Transmembrane protein 41B/Stasimon (human TMEM41B theoretical molecular weight 32.5 kDa) is an integral endoplasmic reticulum membrane protein that plays a role in autophagy and neurogenesis (1). TMEM41B forms a complex with vacuole membrane protein 1 (VMP1) and is required for autophagosome formation. Similar to VMP1, TMEM41B contains a VTT domain. Expression of TMEM41B/Stasimon restores motor neuron function defects in Drosophila and zebrafish models of spinal muscular atrophy (SMA). Survival motor neuron protein (SMN) deficiency, which underscores the neuromuscular disorder SMA, affects TMEM41B/Stasimon U12 splicing and mRNA expression (2,3).
