[Function of Tra2beta1 proteins in the splicing of neural-specific genes].
The in vitro studies have shown that Tra2beta1 proteins are important regulators in the alternative pre-mRNA splicing in mammalians. To date, the knowledge regarding the in vivo function of Tra2beta1 proteins, especially the function in regulating the splicing of neural-specific genes and the cell-type specificity of the functions is very limited. In the present study, the cell-type specific splicing of two neural-specific genes (GluR-B and SMN2), and the function of Tra2beta1 proteins in regulation of the splicing were studied in two types of cells (COS-1 and PFSK-1) using in vivo splicing models. The results showed that the splicing of GluR-B and SMN2 minigenes is cell-type specific, while Tra2beta1 proteins regulate the splicing of the minigenes in both cell lines in a similar pattern. It indicates that the Tra2beta1-regulated splicing of GluR-B and SMN2 minigenes regulated by Tra2beta1 is not cell-type specific.
