Protein
U6 snRNA phosphodiesterase
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Phosphodiesterase responsible for the U6 snRNA 3' end processing. Acts as an exoribonuclease (RNase) responsible for trimming the poly(U) tract of the last nucleotides in the pre-U6 snRNA molecule, leading to the formation of mature U6 snRNA 3' end-terminated with a 3'phosphate. Could be involved in aerobic respiration.
Similarity
Belongs to the 2H phosphoesterase superfamily. USB1 family.
