March-I v2 has a very short 5′-UTR
A, 5′ RACE was performed using mRNA isolated from mouse spleen DCs. The length of the 5′-UTR (relative to the initiation codon) for nine independent clones was identified by DNA sequence analysis. B, 12 different March-I ESTs were aligned to the March-I v2 coding sequence, and the length of the 5′-UTR (relative to the initiation codon) was determined. The GenBank ID for each EST is indicated. The average ± S.D. for each set of analyses is shown.
