Abstract

RIM1 is a putative effector protein for Rab3s, synaptic GTP-binding proteins. RIM1 is localized close to the active zone at the synapse, where it interacts in a GTP-dependent manner with Rab3 located on synaptic vesicles. We now describe a second RIM protein, called RIM2, that is highly homologous to RIM1 and also expressed primarily in brain. Like RIM1, RIM2 contains an N-terminal zinc finger domain that binds to Rab3 as a function of GTP, a central PDZ domain, and two C-terminal C(2) domains that are separated by long alternatively spliced sequences. Unexpectedly, the 3'-end of the RIM2 gene produces an independent mRNA that encodes a smaller protein referred as NIM2. NIM2 is composed of a unique N-terminal sequence followed by the C-terminal part of RIM2. Data bank searches identified a third RIM/NIM-related gene, which encodes a NIM isoform referred to as NIM3; no RIM transcript from this gene was detected. To test if NIMs, like RIMs, may function in secretion, we investigated the effect of NIM3 on calcium-triggered exocytosis in PC12 cells. NIM3 induced a dramatic increase in calcium-evoked exocytosis (50%), with no significant effect on base-line release, suggesting that NIMs, like RIMs, regulate exocytosis The combination of conserved and variable sequences in RIMs and NIMs indicates that the individual domains of these proteins provide binding sites for interacting molecules during exocytosis, as shown for the zinc finger domain of RIM, which binds to GTP-bound Rab3s.…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
