VAPB Aggregates and Neurodegeneration

  • P. Skehel


VAP proteins are a small family of type II membrane proteins enriched on the endoplasmic reticulum that have been conserved from yeast to mammals. The N-terminal half of the proteins consists of a domain highly homologous to a polypeptide found in the motile sperm of nematodes known as the major sperm protein (MSP). A mis-sense mutation in human vapB that changes a proline residue to a serine in the most highly conserved region of the MSP domain causes a rare form of motor neuron disease, amyotrophic lateral sclerosis type 8. Whether vapB P56S is a gain or loss of function mutation is not yet clear, however, it causes the protein to aggregate and may disrupt the normal function and regulation of the ER.
