Gemin5 is a component of the SMN (survival of motor neurons) complex. The SMN complex is composed of the SMN protein and several Gemins (2-7) and is involved in the assembly of snRNPs in the cytoplasm and their transport to the nucleus. The SMN complex localizes to nuclear focal structures called gems or Gemini of coiled bodies. Gemin 5 has been shown to be responsible for recognizing and binding the snRNP code during snRNP biogenesis. Recent studies have shown that Gemin 5 is rarely detectable in SMN complexes associated with gems/Cajal bodies in the nucleus and may play a specific role in cytoplasmic SMN complexes. It has also been shown to function as a scaffold protein for ASK1-JNK1 signaling.
