We have characterized five human gamma-crystallin genes isolated from a genomic phage library. DNA sequencing of four of the genes revealed that two of them predict polypeptides of 174 residues showing 71% homology in their amino acid sequence; the other two correspond to closely related pseudogenes which contain the same in-frame termination codon at identical positions in the coding sequence. Two of the genes and one of the pseudogenes are oriented in a head-to-tail fashion clustered within 22.5 kilobases. All three contain a TATA box 60 to 80 base pairs upstream of the initiation codon and a highly conserved segment of 44 base pairs in length immediately preceding the TATA box. The two genes and the two pseudogenes are similar in structure: each contains a small 5' exon encoding three amino acids followed by two larger exons that correspond exactly to the two similar structural domains of the polypeptide. The first intron varies from 100 to 110 base pairs, and the second intron ranges from 1 to several kilobases, rendering an overall gene size of 1.7 to 4.5 kilobases. At least one of the two pseudogenes appears to have been functional before inactivation, suggesting that their identical mutation was generated by gene conversion. 相似文献

The 5' and 3' flanking regions of the yeast actin gene have been sequenced and the ends of the actin mRNA were determined by the single-strand nuclease mapping procedure. The mRNA starts with a pyrimidine residue 141 (or 140) nucleotides upstream from the initiation codon. The actin gene lacks a typical "TATA" box 30 base pairs upstream from the mRNA start site but it contains a region homologous to the canonical sequence 5'-GGCTCAATCT-3' which is found in several eukaryotic genes 70 to 80 bp upstream from the mRNA cap site. Judging from the S1 nuclease mapping, there are two populations of actin mRNA terminating 98 and 107 nucleotides downstream from the stop codon. The 3' termini are preceded by three AATAAA sequences found in most eukaryotic polyadenylated mRNAs. 相似文献

The upstream region of the PSS gene contains three positive cis-acting elements, upstream activation sequences 1 and 2 (UAS1 and UAS2) and a TATA box. The 5' end of UAS1 occurs between positions -239 and -209, and that of UAS2 is between positions -172 and -164. UAS2 contains 5'-TTCACATG-3' as a core sequence at positions -161 to -154. Mutational analysis revealed that this octamer is responsible for the control of PSS expression by inositol and choline. The TATA box is located at positions -112 to -108. In addition, PSS contains a negative cis-acting sequence between UAS2 and the TATA box. 相似文献
