Porcine gene-specifi c primers design Four alternatively spliced transcript variants of TRIM55 have been identifi ed in human. The longest human TRIM55 cDNA (transcript variant 2, GenBank accession number: NM_033058) was used to search in the ‘EST_other’ database with the standard BLAST (http://www.ncbi. nlm.nih.gov/blast/) algorithm for homologous pig expressed sequence tags (ESTs). The ESTs s...

Description The gene contains five exons and four introns; it is composed of a variable 5' untranslated region, a 296 bp coding sequence, a 3' untranslated region and a polyA tail. Transcription The gene has 5 alternatively spliced variants encoding the same protein; the variant 1 represents the longest transcript (951 bp), all the other variants have distinct and shorter 5'UTR as compared to v...

In the human genome, the majority of protein-encoding genes are interrupted by introns, which are removed from primary transcripts by a macromolecular enzyme known as the spliceosome. Spliceosomes can constitutively remove all the introns in a primary transcript to yield a fully spliced mRNA or alternatively splice primary transcripts leading to the production of many different mRNAs from one g...

Utrophin is a 400 kDa autosomal homolog of dystrophin and a component of the submembranous cytoskeleton. While multiple dystrophin isoforms have been identified along with alternatively spliced products, to date only two different mRNA species of utrophin have been identified. To determine the degree of evolutionary conservation between dystrophin and utrophin isoforms, we have compared their e...

In Arabidopsis, pre-mRNAs encoding serine/arginine (SR) proteins, key regulators of constitutive and alternative splicing, are extensively alternatively spliced. In seedlings, 13 SR genes are alternatively spliced to generate 75 transcripts, of which 53 contain a premature termination codon (PTC). However, it is not known if any of the PTC-containing splice variants are the targets of nonsense-...

The wild-type p53 gene has been widely implicated in the regulation of hypermethylated in cancer-1 (HIC-1) transcription, a master growth regulatory gene with multiple promoters and, consequently, multiple alternatively spliced transcripts. We investigated the role of p53 (wild type and mutant, both endogenous and exogenous) in modulating the various HIC-1 transcripts. We discovered a novel uns...
