A brain phosphatase with specificity for microtubule-associated protein- 2
CL Patterson Jr and M Flavin
A protein phosphatase has been isolated from brain using, as assay
substrate throughout the purification, microtubule-associated protein-2
which had been phospho-labeled by its associated kinase. In contrast to
other protein phosphatases, this phosphatase can effectively release
phosphate from both the microtubule-binding and projection domains of
microtubule-associated-protein-2. This enzyme appears to be a distinct,
specific phosphatase that does not readily fit into previous classification
schemes and is possibly the enzyme responsible for dephosphorylating
microtubule-associated protein-2 in vivo.
