ELAV-like protein HuD overexpression and pulldown (perro-affy-mouse-482241)

Post-transcriptional mechanisms play an important role in the control of gene expression. RNA-binding proteins are key players in the post-transcriptional control of many neural genes and they participate in multiple processes, from RNA splicing and mRNA transport to mRNA stability and translation. Our laboratory has developed the first mouse model overexpressing a RNA-binding protein, the ELAV-like protein HuD, in the CNS under the control of the CaMKinII alpha promoter. Initial behavioral characterization of the mice revealed that they had significant learning deficits together with abnormalities in prepulse inhibition (PPI). At the molecular level, we found that the expression of the growth-associated protein GAP-43, one of the targets of HuD, was increased in the hippocampus of HuD transgenic mice.
