  • Function
    Pre-mRNA-binding protein required for splicing of both U2- and U12-type introns. Selectively interacts with the 3'-splice site of U2- and U12-type pre-mRNAs and promotes different steps in U2 and U12 intron splicing. Recruited to U12 pre-mRNAs in an ATP-dependent manner and is required for assembly of the prespliceosome, a precursor to other spliceosomal complexes. For U2-type introns, it is selectively and specifically required for the second step of splicing.
  • Tissue specificity
    Widely expressed.
  • Sequence similarities
    Contains 2 C3H1-type zinc fingers.

Thank you very much for your interest in our antibodies.

I can confirm that both antibodies are not tested and guaranteed for mouse samples.

We usually expect an cross-reaction of an antibody when the immunogne shows 85% or more hom...

Thank you for your email.

The immunogen of ab50753 also show similarity with mouse >90% so this antibody would also react with mouse samples.

I hope this bit of information will also be helpful.

Thank you for contacting us.

The cross reactivity info we have for these products is entirely based on the sequence homology between human and mouse. The immunogen of ab94951 is about 88% (Blast homology) similar to the mouse sequence so thi...
