Applications

Our Abpromise guarantee covers the use of ab155054 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
WB 1/500 - 1/3000. Predicted molecular weight: 31 kDa.
IHC-P 1/100 - 1/1000.
ICC/IF 1/100 - 1/1000.

Target

  • Function
    Binds stem loop II of U1 snRNA. It is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process.
  • Sequence similarities
    Belongs to the RRM U1 A/B'' family.
    Contains 2 RRM (RNA recognition motif) domains.
  • Cellular localization
    Nucleus.
