Heterogeneity of 5' untranslated region (5'UTR) sequences is a common feature of growth hormone receptor/binding protein (GHR/BP) mRNA from a number of species. Two major 5'UTR sequences (designated L1 and L2 in the mouse) have been cloned from rodents, ruminants and primates, and are known to correspond to transcripts generated from independently regulated promoters. A variable number of other 5'UTRs with diverse sequences have been cloned from rat, human and bovine tissues. To characterize alternative 5'UTR usage in mouse GHR/BP mRNA, we carried out 5' rapid amplification of cDNA ends using RNA from non-pregnant mouse liver and adipose tissue. Three novel 5'UTR sequences were obtained. Sequencing of genomic DNA revealed that exons corresponding to these three sequences are clustered within 1 kb downstream of the exon encoding 5'UTR L2, and the associated L2 promoter. The novel 5'UTRs are present at very low levels relative to the total pool of GHR/BP mRNA in liver, fat, kidney, and mammary gland as determined by ribonuclease protection assays. On the basis of these data, we propose that these 5'UTR sequences may result from the use of cryptic transcription start sites and splice donor sites under the influence of the adjacent L2 promoter/enhancer region.
