Clr4, a highly conserved SUV39 histone methyltransferase, requires its SET domain to sense histone H3K14 ubiquitination in order to maintain heterochromatin and H3K9 methylation.
Simultaneous phosphorylation of multiple substrate motifs drives switch-like target recognition and monoubiquitylation by an E3 ligase during metazoan development.
Negative Gravitropic Response of roots (NGRs), pivotal for root gravitropic bending, are indispensable for the gravity-induced translocation of D6 protein kinase, a key regulator of PIN3 auxin efflux carrier activity.
The physicochemical interactions among wild-type nucleosomes hold substantial significance and play a role in chromatin folding under physiological salt concentrations.
Isw1 acts as a master regulator in modulating the expression of drug-resistance genes, and this regulatory mechanism is dependent on the interaction of Isw1 acetylation and ubiquitination.

Vitamin D bound to its receptor interacts with SIRT1 to induce its auto deacetylation and catalytic activity, which drives anti-proliferative effects in colorrectal cancer and this may lead to new therapeutic approaches for colorrectal and perhaps other cancers.
An aspartyl protease is essential for the lytic cycle of Toxoplasma gondii and is involved in the maturation of proteins critical for invasion and egress, and it can be targeted selectively with an ethylamine scaffold based peptidomimetic inhibitor.
Noncanonical usage of stop codons in ciliates expands structurally flexible Q-rich domains and coevolves with codon usage biases to avoid triplet repeat disorders mediated by CAG/GTC replication slippage.

Post-phosphoryl modification of α-dystroglycan requires the glucuronyltransferase B4GAT1; this enzyme synthesizes the acceptor glycan that serves as a primer for the glycosyltransferase LARGE to synthesize the laminin-binding glycan.
