Rem2 stabilizes intrinsic excitability and spontaneous firing in visual circuits.
Title: Rem2 stabilizes intrinsic excitability and spontaneous firing in visual circuits.
When rats become maternal, they increase the expression of Rem2 in the medial preoptic area which inhibits dendritic complexity and associates with an enhancement of maternal responsiveness.
Title: Maternal care associates with differences in morphological complexity in the medial preoptic area.
Rem2 is regulated at the transcriptional level by calcium influx and inhibits dendritic arborization in cultured rat cortical neurons
Title: Rem2 is an activity-dependent negative regulator of dendritic complexity in vivo.
Rem2 has a role in neuronal plasticity hrough co-trafficking with CaMKIIa
Title: Activity-dependent subcellular cotrafficking of the small GTPase Rem2 and Ca2+/CaM-dependent protein kinase IIα.
structure of the Rem2 G domain bound to GDP is reported here in a monoclinic crystal form at 2.66 A resolution

molecular mechanisms by which Rem2 knockdown affected synaptogenesis and Ca(2) homeostasis in cultured rat hippocampal neurons
Title: Rem2-targeted shRNAs reduce frequency of miniature excitatory postsynaptic currents without altering voltage-gated Ca²⁺ currents.
our results suggest that Rem2 regulates dendritic branching and synapse development
Title: The GTPase Rem2 regulates synapse development and dendritic morphology.
Voltage dependant calcium channels blockade by Rem2 is likely to be controlled by both the localized concentration of membrane phosphorylated phosphatidylinositide lipids and direct 14-3-3 binding to the Rem2 C-terminus.
Title: Analysis of the Rem2 - voltage dependant calcium channel beta subunit interaction and Rem2 interaction with phosphorylated phosphatidylinositide lipids.
Rem2 localizes to the plasma membrane via a C-terminal motif and interacts with calcium channel beta subunits in the preassembled N-type channel, thereby forming a nonconducting species.
Title: Expression of Rem2, an RGK family small GTPase, reduces N-type calcium current without affecting channel surface density.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
