Genomic organization and alternative splicing of SLC4A9. Sequence coordinates refer to nucleotide positions on two different draft-phase contigs of BAC CTC-329D1, GenBank AC008438.1 [gi: 5686628]. The first six rows after the heading row present all the putative coding isoforms, in order of decreasing known length. The bottom eight rows present the noncoding isoforms (including clones whose coding potential could not be determined because of insufficient available sequence). The sixth coding isoform is an IMAGE clone from the NCI CGAP kid11 kidney cDNA library (IMAGE: 2696136). For the noncoding isoforms, the first and second clones from the bottom are IMAGE clones from the NCI CGAP kid11 kidney cDNA library (IMAGE: 2384256 and 2379164, respectively). The fourth clone from the bottom was isolated from the Clontech long-insert fetal brain cDNA library. All other clones were isolated from the Clontech long-insert adult kidney cDNA library.
