General description

Anti-Splicing Factor SC-35 antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the SC-35 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a RBF-DHJ mouse immunized with partially purified spliceosomes prepared from HeLa cells. Splicing Factor SC-35, also known as serine/arginine rich splicing factor 2 (SRSF2) belongs to the family of of serine/arginine-rich (SR) proteins.

Immunogen

partially purified spliceosomes prepared from HeLa cells

Application

Anti-Splicing Factor SC-35 antibody has been used in
  • dot blot
  • enzyme linked immunosorbent assay (ELISA)
  • immunofluorescence
  • immunohistochemistry
  • immunoblotting
  • immunoprecipitation

Biochem/physiol Actions

Splicing Factor SC-35 are critical regulators of constitutive and alternative pre-mRNA splicing. It also controls cellular apoptosis in response to genotoxic stress. Serine/arginine protein kinase 1 (SRPK1) specifically phosphorylates SC-35, resulting in p53 suppression and cyclin D1 upregulation. Elevated levels of SC-35 correlate with aggressive phenotype in several cancer types including lung squamous cell carcinoma and lung adenocarcinoma. SC-35 has oncogenic function in tumor progression of human papilloma virus (HPV)-infected cells.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Nuclear speckles are non-membrane-bound organelles known as storage sites for messenger RNA (mRNA) processing and splicing factors. More recently, nuclear speckles have also been implicated in splicing and export of a subset of mRNAs, including the influenza virus M mRNA
