{"symbol":"CPSF3","synonyms":["CPSF-73","CPSF73"],"name":"cleavage and polyadenylation specific factor 3, 73kDa","description":"This gene encodes a member of the metallo-beta-lactamase family. The encoded protein is a 73kDa subunit of the cleavage and polyadenylation specificity factor and functions as an endonuclease that recognizes the pre-mRNA 3\u0027-cleavage site AAUAAA prior to polyadenylation. It also cleaves after the pre-mRNA sequence ACCCA during histone 3\u0027-end pre-mRNA processing.
