Protein attributes

Sequence length	125 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Necessary for the splicing of pre-mRNA. Directly contacts the pre-mRNA branch site adenosine for the first catalytic step of splicing. Enters the spliceosome and associates with the pre-mRNA branch site as part of the 17S U2 or, in the case of the minor spliceosome, as part of the 18S U11/U12 snRNP complex, and thus may facilitate the interaction of these snRNP with the branch sites of U2 and U12 respectively By similarity.
Subunit structure	Interacts with SF3B1/SF3b155. Interacts to a lesser extent with SF3b130 By similarity.
Subcellular location	Nucleus Potential.
Sequence similarities	Contains 1 RRM (RNA recognition motif) domain.
