The comparison of related genomes has emerged as a powerful lens for genome interpretation. Here we report the sequencing and comparative analysis of 29 eutherian genomes. We confirm that at least 5.5% of the human genome has undergone purifying selection, and locate constrained elements covering approximately 4.2% of the genome. We use evolutionary signatures and comparisons with experimental data sets to suggest candidate functions for approximately 60% of constrained bases. These elements reveal a small number of new coding exons, candidate stop codon readthrough events and over 10,000 regions of overlapping synonymous constraint within protein-coding exons. We find 220 candidate RNA structural families, and nearly a million elements overlapping potential promoter, enhancer and insulator regions. We report specific amino acid residues that have undergone positive selection, 280,000 non-coding elements exapted from mobile elements and more than 1,000 primate- and human-accelerated elements. Overlap with disease-associated variants indicates that our findings will be relevant for studies of human biology, health and disease.
We have isolated and sequenced cDNA clones covering the entire coding sequence and short flanking regions of guinea pig lipoprotein lipase. The expression cDNA library used was constructed in lambda gt11 with mRNA derived from adipocytes. The deduced amino acid (aa) sequence starts with a stretch of 17 aa interpreted as a leader peptide. The open reading frame continues with 448 aa residues and ends with a TGA stop codon. Combined with previous data this information allows the assignment of domains in the lipase molecule. A likely candidate for the heparin-binding site is a 9-aa stretch containing five positive charges, analogous to the consensus sequence for receptor-binding sites on apolipoproteins E and B. A previously noted homology to pancreatic lipase is extended. Analysis of polyadenylated RNA from several tissues indicated a high level of expression in adipocytes, heart muscle and mammary gland. No lipoprotein lipase mRNA could be detected in liver. Northern blots revealed three major mRNAs with sizes corresponding to 3.8 kb, 3.3 kb and 2.1 kb, respectively. In adipocytes and heart muscle a fourth mRNA, with an estimated size of 4.5 kb, was also detected. Analysis of genomic DNA by Southern blotting indicated a single gene locus coding for lipoprotein lipase. Hence, modification of the primary transcript seems to be involved in the production of the various mRNAs.
