Coronin 1 regulates cognition and behavior through modulation of cAMP/protein kinase A signaling.

ABSTRACT: Cognitive and behavioral disorders are thought to be a result of neuronal dysfunction, but the underlying molecular defects remain largely unknown. An important signaling pathway involved in the regulation of neuronal function is the cyclic AMP/Protein kinase A pathway. We here show an essential role for coronin 1, which is encoded in a genomic region associated with neurobehavioral dysfunction, in the modulation of cyclic AMP/PKA signaling. We found that coronin 1 is specifically expressed in excitatory but not inhibitory neurons and that coronin 1 deficiency results in loss of excitatory synapses and severe neurobehavioral disabilities, including reduced anxiety, social deficits, increased aggression, and learning defects. Electrophysiological analysis of excitatory synaptic transmission in amygdala revealed that coronin 1 was essential for cyclic-AMP-protein kinase A-dependent presynaptic plasticity. We further show that upon cell surface stimulation, coronin 1 interacted with the G protein subtype G?s to stimulate the cAMP/PKA pathway. The absence of coronin 1 or expression of coronin 1 mutants unable to interact with G?s resulted in a marked reduction in cAMP signaling. Strikingly, synaptic plasticity and behavioral defects of coronin 1-deficient mice were restored by in vivo infusion of a membrane-permeable cAMP analogue. Together these results identify coronin 1 as being important for cognition and behavior through its activity in promoting cAMP/PKA-dependent synaptic plasticity and may open novel avenues for the dissection of signal transduction pathways involved in neurobehavioral processes.

Project description:The neurotrophic peptide PACAP (pituitary adenylate cyclase-activating polypeptide) elevates cAMP in PC12 cells. Forskolin and dibutyryl cAMP mimic PACAP's neuritogenic and cell morphological effects, suggesting that they are driven by cAMP. Comparison of microarray expression profiles after exposure of PC12 cells to either forskolin, dibutyryl cAMP, or PACAP revealed a small group of cAMP-dependent target genes. Neuritogenesis induced by all three agents is protein kinase A (PKA)-independent [not blocked by N-[2-(4-bromocinnamylamino)ethyl]-5-isoquinoline (H89)] and extracellular signal-regulated kinase (ERK)-dependent [blocked by 1,4-diamino-2,3-dicyano-1,4-bis(methylthio) butadiene (U0126)], and therefore cAMP-dependent target genes potentially mediating neuritogenesis were selected for further analysis based on the pharmacological profile of their induction by PACAP (i.e., mimicking that of neuritogenesis). Small interfering RNA (siRNA) targeting one of these genes, Egr1, blocked PACAP-induced neuritogenesis, and siRNA targeting another, Vil2, blocked a component of the cell size increase elicited by PACAP. Neither siRNA blocked PACAP's PKA-dependent antiproliferative effects. PACAP signaling to neuritogenesis was also impaired by dominant-negative Rap1 expression but was not affected by inhibition of protein kinase C (PKC), indicating a G-protein-coupled receptor-mediated differentiation pathway distinct from the one activated by receptor tyrosine kinase ligands such as nerve growth factor (NGF), that involves both Rap1 and PKC. We have thus identified a cAMP-dependent, PKA-independent pathway proceeding through ERK that functions to up-regulate the transcription of two genes, Egr1 and Vil2, required for PACAP-dependent neuritogenesis and increased cell size, respectively. Dominant-negative Rap1 expression impairs both PACAP-induced neuritogenesis and Egr1 activation by PACAP, suggesting that cAMP elevation and ERK activation by PACAP are linked through Rap1.

Project description:The communication mechanism(s) responsible for the allosteric behavior of E.coli cAMP binding receptor protein, CRP, is still a subject of intense investigation. As a tool to explore the communication mechanism, the mutations at various positions in the cAMP-binding (K52N, D53H, S62F and T127L) or the DNA- binding (H159L) domain or both (K52N/H159L) were generated. The sites and specific nature of side chain substitutions were defined by earlier genetic studies, the results of which show that these mutants have a similar phenotype i.e. they are activated without exogenous cAMP. Presently, no significant changes in the structures of WT and mutant CRPs have been observed. Hence, the pressing issue is to identify a physical parameter that reflects the effects of mutations. In this study, the stability of these various CRP species in the presence of GuHCl was monitored by three spectroscopic techniques, namely, CD, tryptophan fluorescence and FT-IR which could provide data on the stability of α-helices and β-strands separately. Results of this study led to the following conclusions: 1. The α-helices can be grouped into two families with different stabilities. Mutations exert a differential effect on the stability of helices as demonstrated by a biphasic unfolding curve for the helices. 2. Regardless of the locations of mutations, the effects can be communicated to the other domain resulting in a perturbation of the stability of both domains, although the effects are more significantly expressed in the stability of the helices. 3. Although in an earlier study [Gekko, et al. Biochemistry 43 (2004) 3844] we showed that cooperativity of cAMP binding is generally correlated to the global dynamics of the protein and DNA binding affinity, in this study we found that generally there is no clear correlation between functional energetics and stability of secondary structures. Thus, results of this study imply that modulation of allostery in CRP is entropic in nature.
