Table 1.
Top: genomic sequence of COX-2 3′-UTR containing three polyadenylation signals is depicted schematically. The position of proximal 1 is arbitrarily set as 0. Closed diamonds denote the locations of poly(A) signals supported by ESTs with poly(A) tail sequence. Open circles are the locations of the 3′ end of ESTs without poly(A) tail sequence. Bottom: LIB_ID corresponds to cDNA library ID in the dbEST database. P1, proximal 1; P2, proximal 2; D, distal; and D1, distal supported by ESTs without poly(A) tail sequence (explained in the text).
