abstract = {The calcium ion regulates many aspects of neuronal
migration, which is an indispensable process in the
development of the nervous system. Calmodulin (CaM) is a
multifunctional calcium ion sensor that transduces much of
the signal. To better understand the role of Ca(2+)-CaM in
neuronal migration, we investigated mouse precerebellar
neurons (PCNs), which undergo stereotyped, long-distance
migration to reach their final position in the developing
hindbrain. In mammals, CaM is encoded by three non-allelic
CaM (Calm) genes (Calm1, Calm2 and Calm3), which produce an
identical protein with no amino acid substitutions. We found
that these CaM genes are expressed in migrating PCNs. When
the expression of CaM from this multigene family was
inhibited by RNAi-mediated acute knockdown, inhibition of
Calm1 but not the other two genes caused defective PCN
migration. Many PCNs treated with Calm1 shRNA failed to
complete their circumferential tangential migration and thus
failed to reach their prospective target position. Those
that did reach the target position failed to invade the
depth of the hindbrain through the required radial
migration. Overall, our results suggest the participation of
CaM in both the tangential and radial migration of PCNs.},
