9.B.17 The VAMP-associated protein (VAP) Family

The VAMP-associated proteins (VAPs) are highly conserved integral endoplasmic reticulum membrane proteins implicated in diverse cellular functions, including the regulation of lipid transport and homeostasis, membrane trafficking, neurotransmitter release, stabilization of presynaptic microtubules, and the unfolded protein response. Recently, a single missense mutation within the human VAP-B gene was identified in three forms of familial motor neuron disease. Yeast, flies and mammals have VAPs. There is a network of VAP-interacting proteins. Their mechanisms of actin are not well understood (Lev et al., 2008).
