摘要
本研究组(Choudhuri et al., 2000)和Cattori et al.(2000)分别克隆了大鼠肝脏特异性有机阴离子转运蛋白-1 (rlst-1/Oatp4/Slc21a10)全长编码序列。我们还克隆了rlst-1的一个剪接变体(Choudhuri et al., 2000)。Kakyo等人(1999)克隆了另一个剪接变体。我们还通过筛选BAC- rat文库获得了一个BAC克隆,并确定了外显子断点,从而能够确定剪接变体的起源。自我们最初发表以来,我们进一步表征了rlst-1基因。在这篇文章中,我们报道了rlst-1基因50侧序列中含有启动子的约2.3 kb的序列。我们绘制了转录起始位点以确定启动子的精确位置。本文还报道了rlst-1基因的剪接连接序列、部分序列和内含子长度。最后,我们分析了rlst-1编码序列的密码子使用偏差。转录起始位点由Choudhuri等人(2001)描述的衣壳克隆确定,有两个主要的修改。首先,使用20mg总RNA(而不是polyA mRNA),其次,使用Gene Racer RLM RACE系统(In Vitrogen, CA)进行实验。基因特异性反向引物(GSP)和巢式基因特异性反向引物(nGSP)的序列如下:
Determination of Transcription Start Site and Analysis of Promoter Sequence, Splice Junction Sites, Intron Sequence and Codon Usage Bias of Rat Liver-specific Organic Anion Transporter-1 (rlst-1/Oatp-4/Slc21a10) Gene
The full-length coding sequence of rat liver specific organic anion transporter-1 (rlst-1/Oatp4/Slc21a10) was cloned by our group (Choudhuri et al., 2000) and by Cattori et al. (2000). We also cloned a splice variant of rlst-1 (Choudhuri et al., 2000). Another splice variant was cloned by Kakyo et al. (1999). We had also obtained a BAC clone from screening a BAC-Rat library, and determined the exon breakpoints to be able to determine the origin of the splice variants. Since our original publication, we have further characterized the rlst-1 gene. In this communication, we report the sequence of about 2.3 kb of the 50-flanking sequence of the rlst-1 gene that contains the promoter. We have mapped the transcription start site to define the precise location of the promoter. We also report here the splice junction sequence, and the partial sequences and lengths of introns of the rlst-1 gene. Finally, we have analyzed the codon usage bias in the rlst-1 coding sequence. Transcription start site was determined by capsite cloning as described by Choudhuri et al. (2001) with two major modifications. First, 20mg total RNA (instead of polyA mRNA) and secondly, Gene Racer RLM RACE system (In Vitrogen, CA), were used for this experiment. Sequence of the gene specific reverse primer (GSP), and nested gene specific reverse primer (nGSP) used, was as follows:
