Alternative mRNA splicing generates the two ribulosebisphosphate carboxylase/oxygenase activase polypeptides in spinach and Arabidopsis

Sequence analysis of ribulosebisphosphate carboxylase/oxygenase (rubisco) activase cDNA and genomic clones isolated from spinach and Arabidopsis thaliana indicates that the two polypeptides of rubisco activase arise from alternative splicing of a common pre-mRNA. In spinach, two 5' splice sites are used in processing a single 137-nucleotide intron near the 3' end of the primary transcript. This intron was either removed completely or, alternatively, the first 22 nucleotides of the intervening sequence were retained in the mature rubisco activase mRNA. The 22-nucleotide auxiliary exon contains an in-frame ochre termination codon and leads to the synthesis of a 41-kilodalton polypeptide. Removal of the entire 137-nucleotide intervening sequence results in the synthesis of a larger 45-kilodalton polypeptide. Thus, alternative splicing of the spinach rubisco activase mRNA results in the synthesis of two polypeptides that are identical except for 37 additional amino acids at the C terminus of the 45-kilodalton polypeptide. This conclusion was confirmed by Cleveland peptide mapping and by N-terminal and C-terminal amino acid sequence analyses of both purified polypeptides. This method of producing the two rubisco activase polypeptide...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
