Intracellular Immunization against SIVmacUtilizing a Hairpin Ribozyme

open access: yes, 1996
A hairpin ribozyme targeting the 3′ LTR region (9456) of SIVmac239was cloned into a murine retroviral vector. This target sequence is conserved among various SIV, as well as most HIV-2, strains.

CPEB3 is associated with human episodic memory

open access: yesFrontiers in Behavioral Neuroscience, 2009
Cytoplasmic polyadenylation element-binding (CPEB) proteins are crucial for synaptic plasticity and memory in model organisms. A highly conserved, mammalian-specific short intronic sequence within CPEB3 has been identified as a ribozyme with self ...

From Prebiotic Catalysts to Modern Applications: How Early Catalysts Inspire Today's Innovations

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Simple catalytic systems that may have operated under prebiotic conditions offer useful molecular principles for the design of modern functional materials. By examining how amino acids, peptide assemblies, and metal complexes achieve catalysis through simple chemical features, this review highlights how prebiotic chemistry can inspire new strategies ...

Analysis of Self-Cleaving Ribozyme Transition States [PDF]

open access: yes, 2019
Endonucleolytic ribozymes, non-coding RNA molecules capable of self-scission, have been studied for decades. First, because of their novel functionality, and later because their capacity to serve as paradigmatic model systems of RNA catalysis.

Inhibition of Cpeb3 ribozyme elevates CPEB3 protein expression and polyadenylation of its target mRNAs and enhances object location memory

open access: yeseLife
A self-cleaving ribozyme that maps to an intron of the cytoplasmic polyadenylation element-binding protein 3 (Cpeb3) gene is thought to play a role in human episodic memory, but the underlying mechanisms mediating this effect are not known. We tested the

Evidence for the involvement of Gi2 in activation of extracellular signal-regulated kinases in hepatocytes

open access: yesBMC Cell Biology, 2001
Background Activation of the extracellular signal-regulated kinases ERK1 and ERK2 in hepatocytes by prostaglandin (PG)F2α was recently found to be inhibited by pertussis toxin (PTX) suggesting a role for Gi proteins. Results Targeting the Gi2α expression

Efficient CRISPR‐Cas9 delivery and transgene‐free multiplex genome editing in plants using cymbidium mosaic virus‐derived vectors

open access: yesThe Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY Virus‐induced genome editing (VIGE) has become a useful method by enabling transient delivery of gene‐editing reagents; however, many viral systems face limitations in cargo size, host range, or reliance on transgenic Cas9‐expressing plants.

A Selected Ribozyme Catalyzing Diverse Dipeptide Synthesis

open access: yes, 2002
The sequence of events by which protein, RNA, and DNA emerged during early biological evolution is one of the most profound questions regarding the origin of life.

Efficient inhibition of hepatitis B virus replication by hepatitis delta virus ribozymes delivered by targeting retrovirus

open access: yesVirology Journal, 2010
Background Hepatitis delta virus (HDV) ribozyme is an attractive molecular tool that can specifically recognize and catalyze the self-cleavage of the viral RNA phosphodiester backbone.
