RNA triphosphatase-mediated mRNA capping is essential for maintaining transcript homeostasis and the survival of Toxoplasma gondii [PDF]

open access: yesNature Communications
RNA modifications are crucial for gene expression in eukaryotes; however, the regulatory role of 5’ 7-methylguanosine (m7G) cap, the first modification of mRNA, remains unknown in the protozoan parasite Toxoplasma gondii.

Hydrogen peroxide yields mechanistic insights into human mRNA capping enzyme function. [PDF]

open access: yesPLoS ONE, 2017
Capping of nascent RNA polymerase II (Pol II) transcripts is required for gene expression and the first two steps are catalyzed by separate 5' triphosphatase and guanylyltransferase activities of the human capping enzyme (HCE).

Erythrocyte inosine triphosphatase activity is decreased in HIV-seropositive individuals. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND:Inosine triphosphatase (ITPase) is encoded by the polymorphic gene ITPA and maintains low intracellular levels of the inosine nucleotides ITP and dITP. The most frequently reported polymorphisms are ITPA c.94C>A (rs 1127354) and ITPA c. 124+21

Functional Adaptation of Vocalization Revealed by Morphological and Histochemical Characteristics of Sonic Muscles in Blackmouth Croaker (Atrobucca nibe)

open access: yesBiology, 2022
Sound production in the blackmouth croaker (Atrobucca nibe) was characterized using acoustic, morphological, and histochemical methods. Their calls consisted of a train of two to seven pulses; the frequency ranged from 180 to 3000 Hz, with a dominant ...
