| T1 |
0-119 |
Sentence |
denotes |
Two proteins essential for apolipoprotein B mRNA editing are expressed from a single gene through alternative splicing. |
| T2 |
120-275 |
Sentence |
denotes |
Apolipoprotein B (apoB) mRNA editing involves site-specific deamination of cytidine to form uridine, resulting in the production of an in-frame stop codon. |
| T3 |
276-452 |
Sentence |
denotes |
Protein translated from edited mRNA is associated with a reduced risk of atherosclerosis, and hence the protein factors that regulate hepatic apoB mRNA editing are of interest. |
| T4 |
453-587 |
Sentence |
denotes |
A human protein essential for apoB mRNA editing and an eight-amino acid-longer variant of no known function have been recently cloned. |
| T5 |
588-758 |
Sentence |
denotes |
We report that both proteins, henceforth referred to as ACF64 and ACF65, supported APOBEC-1 (the catalytic subunit of the editosome) equivalently in editing of apoB mRNA. |
| T6 |
759-816 |
Sentence |
denotes |
They are encoded by a single 82-kb gene on chromosome 10. |
| T7 |
817-961 |
Sentence |
denotes |
The transcripts are encoded by 15 exons that are expressed from a tissue-specific promoter minimally contained within the -0.33-kb DNA sequence. |
| T8 |
962-1061 |
Sentence |
denotes |
ACF64 and ACF65 mRNAs are expressed in both liver and intestinal cells in an approximate 1:4 ratio. |
| T9 |
1062-1191 |
Sentence |
denotes |
Exon 11 is alternatively spliced to include or exclude 24 nucleotides of exon 12, thereby encoding ACF65 and ACF64, respectively. |
| T10 |
1192-1349 |
Sentence |
denotes |
Recognition motifs for the serine/arginine-rich (SR) proteins SC35, SRp40, SRp55, and SF2/ASF involved in alternative RNA splicing were predicted in exon 12. |
| T11 |
1350-1519 |
Sentence |
denotes |
Overexpression of these SR proteins in liver cells demonstrated that alternative splicing of a minigene-derived transcript to express ACF65 was enhanced 6-fold by SRp40. |
| T12 |
1520-1655 |
Sentence |
denotes |
The data account for the expression of two editing factors and provide a possible explanation for their different levels of expression. |
