Members of the calmodulin-binding transcription activator (CAMTA) family of proteins function as calcium-sensitive regulators of gene expression in multicellular organisms ranging from plants to humans. Here, we show that global or nervous system deletion of CAMTA1 in mice causes severe ataxia with Purkinje cell degeneration and cerebellar atrophy, partially resembling the consequences of haploinsufficiency of the human CAMTA1 locus. Gene-expression analysis identified a large collection of neuronal genes that were dysregulated in the brains of CAMTA1-mutant mice, and elucidation of a consensus sequence for binding of CAMTA proteins to DNA revealed the association of CAMTA-binding sites with many of these genes. We conclude that CAMTA1 plays an essential role in the control of Purkinje cell function and survival. CAMTA1-mutant mice provide a model to study the molecular mechanisms of neurodegenerative diseases and for screening potential therapeutic interventions for such disorders.
This research output has an Altmetric Attention Score of 8. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 August 2014.
All research outputs
#6,497,307
of 34,526,284 outputs
Outputs from Proceedings of the National Academy of Sciences of the United States of America
#58,896
of 119,110 outputs
Outputs of similar age
#50,711
of 269,776 outputs
Outputs of similar age from Proceedings of the National Academy of Sciences of the United States of America
#559
of 917 outputs
Altmetric has tracked 34,526,284 research outputs across all sources so far. Compared to these this one has done well and is in the 81st percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 119,110 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 40.1. This one has gotten more attention than average, scoring higher than 50% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 269,776 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 81% of its contemporaries.
We're also able to compare this research output to 917 others from the same source and published within six weeks on either side of this one. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
