Arginine methylation regulates telomere length and stability.
TRF2, a component of the shelterin complex, functions to protect telomeres. TRF2 contains an N-terminal basic domain rich in glycines and arginines, similar to the GAR motif that is methylated by protein arginine methyltransferases. However, whether arginine methylation regulates TRF2 function has not been determined. Here we report that amino acid substitutions of arginines with lysines in the...
متن کاملJMJD6 Regulates ERα Methylation on Arginine
ERα functions are tightly controlled by numerous post-translational modifications including arginine methylation, which is required to mediate the extranuclear functions of the receptor. We report that upon oestrogenic stimulation, JMJD6, the only arginine demethylase described so far, interacts with and regulates methylated ERα (metERα) function. Moreover, by combining the silencing of JMJD6 w...
متن کاملO-11: N-a-acetyltransferase 10 Protein Regulates DNA Methylation and Embryonic Development
Background Genomic imprinting is a heritable and developmentally essential phenomenon by which gene expression occurs in an allele-specific manner1. While the imprinted alleles are primarily silenced by DNA methylation, it remains largely unknown how methylation is targeted to imprinting control region (ICR), also called differentially methylated region (DMR), and maintained. Here we show that ...
متن کاملArginine methylation of G3BP1 in response to Wnt3a regulates β-catenin mRNA
Wnt/β-catenin signaling is essential for normal mammalian development. Wnt3a activates the Wnt/β-catenin pathway through stabilization of β-catenin; a process in which the phosphoprotein Dishevelled figures prominently. Protein arginine methylation in signaling complexes containing Dishevelled was investigated. Mass spectrometry of a prominent arginine-methylated, Dishevelled-associated protein...
متن کاملHSP90 regulates DNA repair via the interaction between XRCC1 and DNA polymerase β
Cellular DNA repair processes are crucial to maintain genome stability and integrity. In DNA base excision repair, a tight heterodimer complex formed by DNA polymerase β (Polβ) and XRCC1 is thought to facilitate repair by recruiting Polβ to DNA damage sites. Here we show that disruption of the complex does not impact DNA damage response or DNA repair. Instead, the heterodimer formation is requi...
