Psychiatry related information on RAB3A

In conclusion, we have found no evidence for RAB3A conferring susceptibility on mental retardation in the Han Chinese population [1].

High impact information on RAB3A

PDE4C-containing cosmids also contained the genes for the growth regulatory transcription factor, JUND, and the mini guanine nucleotide regulatory protein, RAB3A [2].
To investigate the possible genetic contribution of the RAB3A gene, we performed a case-control association study focused on the Han population of northwestern China using four common SNPs in the gene (rs7259012, rs17683539, rs2271882, and rs874628) [1].
RAB3A, a Ras-related GTP-binding protein, is found in a rat neuronal cytosol in the form of complex with RabGDI or located on the synaptic vesicles and it cycles between the cytosol and the membranes [3].

Biological context of RAB3A

The RAB3A gene was shown to consist of 5 exons spanning 7.9 kb, while the JUND gene was found to contain no introns [2].
The RAB3A gene is located on chromosome 19p13.11, near a region shown by a linkage study to be involved in the etiology of mental retardation [1].

Associations of RAB3A with chemical compounds

Genomic organisation of the human cyclic AMP-specific phosphodiesterase PDE4C gene and its chromosomal localisation to 19p13.1, between RAB3A and JUND [2].
