The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/100 - 1/500. Epitope exposure is recommended.
Epitope exposure with citrate buffer will enhance staining.
FunctionSplicing factor that in its dephosphorylated form acts as a general repressor of pre-mRNA splicing. Seems to interfere with the U1 snRNP 5'-splice recognition of SNRNP70. Required for splicing repression in M-phase cells and after heat shock. May be involved in regulation of alternative splicing in neurons, with isoform 1 acting as a positive and isoform 3 as a negative regulator.
Tissue specificityWidely expressed.
Sequence similaritiesBelongs to the splicing factor SR family. Contains 1 RRM (RNA recognition motif) domain.
Post-translational modificationsPhosphorylated. Fully dephosphorylated in mitosis and partially dephosphorylated on heat shock. Isoform 3 is phosphorylated on Ser-168.
