25898924 Collybistin forms a complex with mTOR and eIF3 and by sequestering these proteins downregulates mTORC1 signaling and protein synthesis potentially contributing to intellectual disability and autism.
25678704 Impairment of the membrane lipid binding activity of Collybistin R290H and a consequent defect in inhibitory synapse maturation represent a likely molecular pathomechanism of epilepsy and mental retardation in humans.
24297911 The enhancement of Cb-induced gephyrin clustering by GTP-TC10 does not depend on the guanine nucleotide exchange activity of Cb but involves an interaction that resembles reported interactions of other small GTPases with their effectors
22778260 Phosphorylation of gephyrin in hippocampal neurons by cyclin-dependent kinase CDK5 at Ser-270 is dependent on collybistin.
22033413 These results reveal that G(s) and G(q) signalings regulate hPEM-2 functions through PKA and c-Src in Neuro-2a neuroblastoma cells, respectively.
21807943 major regulator of GABAergic postsynaptic gephyrin clustering
21633362 Data indicate that ARHGEF9 is likely to be responsible for syndromic X-linked mental retardation associated with epilepsy.
20622020 Study propose that the collybistin-gephyrin complex has an intimate role in the clustering of GABA(A)Rs containing the alpha2 subunit.
19911011 Observational study of gene-disease association. (HuGE Navigator)
18208356 Results show that hPEM-2 is a target protein of Smurf1.
15215304 translocates gephyrin to submembrane microaggregates; collybistin mutation (G55A)is found in exon 2 of the ARHGEF9 gene in a patient with clinical symptoms of both hyperekplexia and epilepsy
11727829 Here we identified residues critical for interaction with gephyrin in the linker region between the SH3 and the DH domains of collybistin.
