|Background:||The mGluR1b protein is an isoform of the metabotropic glutamate receptor 1 (mGluR1). The mGluR1, together with mGluR5 (both constituting group I of mGluRs), is coupled to the inositol phosphate/Ca[2+] signal transduction pathway, whereas the other five metabotropic glutamate receptors (mGluR2, mGluR3, mGluR4, mGluR6, mGluR7 ) are linked to the inhibition of the cAMP cascade. The highest level of mGluR1 mRNA expression is found in the cerebellar Purkinje cells. Three splicing variants have been described for mGluR1: mGluR1a (alpha), mGluR1b (beta), and mGluR1c. The mGluR1a and mGluR1b functionally differ e.g. in their internalisation responses or in ability to activate the Gs protein pathway, as the mGluR1b lacks a part of C terminus.|
