Absence of neuroanatomical and behavioral deficits in L7/pcp-2-null mice.

L7/pcp-2 is expressed exclusively in cerebellar Purkinje and retinal bipolar neurons. While the function of L7/pcp-2 is unknown, its mRNA is trafficked into dendrites, suggesting a role in dendritic physiology. To elucidate its function, L7/pcp-2-null mice were generated. These mice are neurologically normal with no signs of cerebellar or retinal dysfunction. The mice are indistinguishable from wild-type littermates with regards to gross neuroanatomy and fine structure of Purkinje cell dendrites.
