  text: Alternative splicing in the mGluR5 gene generates two different receptor isoforms,
    of which expression is developmentally regulated. However, little is known about
    the functional significance of mGluR5 splice variants. We have examined the functional
    coupling, subcellular targeting, and effect on neuronal differentiation of epitope-tagged
    mGluR5 isoforms by expression in neuroblastoma NG108-15 cells. We found that both
    mGluR5 splice variants give rise to comparable [Ca2+]i transients and have similar
    pharmacological profile. Tagged receptors were shown by immunofluorescence to
    be inserted in the plasma membrane. In undifferentiated cells the subcellular
    localization of the two mGluR5 isoforms was partially segregated, whereas in differentiated
    cells the labeling largely redistributed to the newly formed neurites. Interestingly,
    we demonstrate that mGluR5 splice variants dramatically influence the formation
    and maturation of neurites; mGluR5a hinders the acquisition of mature neuronal
    traits and mGluR5b fosters the elaboration and extension of neurites. These effects
    are partly inhibited by MPEP.
