Protein attributes

Sequence length	405 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Cleaves the 2'-5' phosphodiester linkage at the branch point of lariat intron pre-mRNAs after splicing and converts them into linear molecules that are subsequently degraded. It thereby facilitates ribonucleotide turnover. It also participates in Ty1 retrovirus-like transposition via a RNA lariat intermediate in cDNA synthesis. Ref.7
Catalytic activity	RNA processing activity that hydrolyzes the 2'-5' phosphodiester linkage at the branchpoint of excised intron lariats.
Subcellular location	Nucleus. Cytoplasm.
Miscellaneous	Present with 1130 molecules/cell in log phase SD medium. Ref.6
Sequence similarities	Belongs to the lariat debranching enzyme family.
