Annotated paper:Schmidt H, et al. "Calbindin D28k targets myo-inositol monophosphatase in spines and dendrites of cerebellar Purkinje neurons" Proc Natl Acad Sci U S A. 2005 Apr 19;102(16):5850-5 PMID:15809430

Annotation description:Prior knowledge (PMID:12176979): IMPA1 (myo-inositol monophosphatase, IMPase) is an enzyme of the inositol-1,4,5-trisphosphate signaling cascade that is activated by the Ca2+-binding protein calbindin D28k (CB).

Using FRAP technique the paper shows that the CB interacts with IMPase in dendritic spines of cerebellar Purkinje, implying that both proteins localise there.
