title: A membrane-associated dimer of acetylcholinesterase from Xenopus skeletal muscle is solubilized by phosphatidylinositol-specific phospholipase C.
abstract: The susceptibility to phosphatidylinositol-specific phospholipase C of the membrane associated acetylcholinesterase (AChE) forms of Xenopus laevis skeletal muscle was examined. This treatment released almost all the detergent-soluble AChE species from muscle homogenates. Sucrose gradient analysis showed that the released acetylcholinesterase form corresponds to a hydrophilic G2 dimer, indicating that this dimer has a glycolipid anchoring domain which contains phosphatidylinositol.
