Regulating synaptic membrane exocytosis 1

RIM1, RIM1alpha, Rab3 effector, CORD7
The protein encoded by this gene is a RAS gene superfamily member that regulates synaptic vesicle exocytosis. This gene also plays a role in the regulation of voltage-gated calcium channels during neurotransmitter and insulin release. Mutations have suggested a role cognition and have been identified as the cause of cone-rod dystrophy type 7. Multiple transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Mar 2012] (from NCBI)

Schmitz et al., Homburg, Germany. In J Neurosci, Oct 2015
Here, we show that active zone proteins RIM1/2 are important regulators of Cav1.4 channel function in mouse rod photoreceptors and thus synaptic activity.

Ptáček et al., Münster, Germany. In Proc Natl Acad Sci U S A, Apr 2015
Here, we show that PNKD interacts with synaptic active zone proteins Rab3-interacting molecule (RIM)1 and RIM2, localizes to synapses, and modulates neurotransmitter release.

Michaut et al., Argentina. In Exp Cell Res, 2012
Here, we report that, like Rab3A, RIM and Munc13 are present in human sperm and that they play a functional role in acrosomal exocytosis before the acrosomal calcium efflux

Molecular in situ topology of Aczonin/Piccolo and associated proteins at the mammalian neurotransmitter release site.
Kilimann et al., Uppsala, Sweden. In Proc Natl Acad Sci U S A, 2011
Data show that Bassoon colocalizes with Aczonin at conventional synapses, but in ribbon synapses, CAST, Munc13, and RIM are segregated from Aczonin, and Aczonin is positioned and may control the access of neurotransmitter vesicles to the fusion site.
