Previously, we identified calcium/calmodulin-dependent protein kinase IIbeta (CaMKIIbeta) mRNA in spinal motor neurons with 372 bp inserted in what corresponds to the "association" domain of the protein. This was interesting because known additions and deletions to CaMKIIbeta mRNA are usually less than 100 bp in size and found in the "variable" region. Changes in the association domain of CaMKIIbeta could influence substrate specificity, activity or intracellular targeting. We show that three variations of this insert are found in CNS neurons or sciatic motor neurons of Sprague-Dawley rats. We used PCR and nucleic acid sequencing to identify inserts of 114, 243, or 372 bases. We also show that addition of the 372 bases is associated with outgrowth of the axon (the standard CaMKIIbeta downregulates when axon outgrowth occurs). Radiolabeling, immunoblots, and 2D PAGE identified this larger CaMKIIbeta as part of the group of soluble proteins moving at the slowest rate of axonal transport (SCa) in sciatic motor neurons (similar1 mm/day). This group is composed mainly of structural proteins (e.g., tubulin) used to assemble the cytoskeleton of regrowing axons.
