High impact information on GEMIN8

  • Gemin8 is also associated with Sm proteins, and Gemin8-containing SMN complexes are competent to carry out snRNP assembly [1].
  • Gemin8 is a novel component of the survival motor neuron complex and functions in small nuclear ribonucleoprotein assembly [1].
  • Here, by mass spectrometry analysis of SMN complexes purified from HeLa cells, we identified a novel protein that is evolutionarily conserved in metazoans, and we named it Gemin8 [1].
  • These results demonstrate that Gemin8 is a novel integral component of the SMN complex and extend the repertoire of cellular proteins involved in the pathway of snRNP biogenesis [1].
  • Here, we have investigated the functional role of Gemin8 using novel monoclonal antibodies against components of the SMN complex and RNA interference experiments [2].

Biological context of GEMIN8


Analytical, diagnostic and therapeutic context of GEMIN8

  • Co-immunoprecipitation and immunolocalization experiments demonstrated that Gemin8 is associated with the SMN complex and is localized in the cytoplasm and in the nucleus, where it is highly concentrated in Gems [1].
