Our Abpromise guarantee covers the use of ab74782 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IP Use at an assay dependent concentration.
ELISA Use at an assay dependent concentration.

Titre using peptide based assay: 1/12500.

WB Use a concentration of 1 µg/ml. Predicted molecular weight: 26 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • FunctionPlays a role in constitutive splicing and can modulate the selection of alternative splice sites. Represses the splicing of MAPT/Tau exon 10.
  • Tissue specificityExpressed at high levels in the heart, kidney, pancreas and placenta, and at lower levels in the brain, liver, lung and skeletal muscle.
  • Sequence similaritiesBelongs to the splicing factor SR family.
    Contains 2 RRM (RNA recognition motif) domains.
  • Post-translational
    Extensively phosphorylated on serine residues in the RS domain.
  • Cellular localizationNucleus. Cellular stresses such as heat shock may induce localization to discrete nuclear bodies termed SAM68 nuclear bodies (SNBs), HAP bodies, or stress bodies. Numerous splicing factors including SRSF1/SFRS1/SF2, SRSF7/SFRS7, SAFB and KHDRBS1/SAM68 accumulate at these structures, which may participate in the post-transcriptional regulation of mRNAs in stressed cells.
