TABLE 3.

Relative presence of the TIA-1 motif in the 5′UTR, CR, and 3′UTR of human genes^a

Data set and parameter	TIA-1 motif in:
	5′UTR	CR	3′UTR
UniGene data set
Total no. of hits	277	914	3,703
Frequency	0.056	0.029	0.203
Experimental data set
Total no. of hits	0	2	70
Frequency	0	0.0087	0.433

^aThe number of motif hits and frequency in the human UniGene database and in the experimental data set were assessed. For each transcript region (5′UTR, CR, and 3′UTR), the total number of hits for the TIA-1 motif and the frequency (number of hits per kilobase) are shown.
