GEMIN4, also named as P97, is a sub-unit of SMN complex. The SMN complex plays a catalyst role in the assembly of small nuclear ribonucleoproteins (snRNPs). It plays an important role in the splicing of cellular pre-mRNAs. The express amount of GEMIN4 is about 8.79 ppm (http://pax-db.org/#!protein/984742). This antibody detects 97-110 kDa GEMIN4.
