TLDR
The construction of a series of vectors is reported that significantly enhance the versatility of this auxin‐inducible degron (AID) system in Saccharomyces cerevisiae and provides evidence for a general usefulness of the system.Abstract:
Fusion of inducible degradation signals, so-called degrons, to cellular proteins is an elegant method of controlling protein levels in vivo. Recently, a degron system relying on the plant hormone auxin has been described for use in yeast and vertebrate cells. We now report the construction of a series of vectors that significantly enhance the versatility of this auxin-inducible degron (AID) system in Saccharomyces cerevisiae. We have minimized the size of the degron and appended a series of additional epitope tags, allowing detection by commercial antibodies or fluorescence microscopy. The vectors are compatible with PCR-based genomic tagging strategies, allow for C- or N-terminal fusion of the degron, and provide a range of selection markers. Application to a series of yeast proteins, including essential replication factors, provides evidence for a general usefulness of the system.read more

Opposing chromatin remodelers control transcription initiation frequency and start site selection

TL;DR: This work shows that many promoters are acted upon by multiple CRs that operate either cooperatively or in opposition to position the key transcription start site-associated +1 nucleosome, and suggests that this reflects a trade-off between maximizing RNA Polymerase II recruitment and minimizing transcription initiation at incorrect sites.

A critical but divergent role of PRDM14 in human primordial germ cell fate revealed by inducible degrons

TL;DR: It is shown that PRDM14 loss results in significantly reduced specification efficiency and an aberrant transcriptome of human PGC-like cells obtained in vitro from human embryonic stem cells (hESCs).

PCNA activates the MutLγ endonuclease to promote meiotic crossing over
Dhananjaya S. Kulkarni,Shannon N Owens,Masayoshi Honda,Masaru Ito,Ye Yang,Mary W. Corrigan,Lan Chen,Aric L. Quan,Neil Hunter,Neil Hunter +9 more
TL;DR: In vivo and in vitro assays with human enzymes show that hPCNA and its loader hRFC are sufficient to activate the hMutLγ endonuclease under physiological conditions and evoke a novel model for crossover-specific dHJ resolution during meiosis.

Sister-chromatid-sensitive Hi-C reveals the conformation of replicated human chromosomes

TL;DR: The rich pattern of sister chromatid topologies and scsHi-C technology will make it possible to dissect how physical interactions between identical DNA molecules contribute to DNA repair, gene expression, chromosome segregation, and potentially other biological processes.

An auxin-based degron system for the rapid depletion of proteins in nonplant cells
TL;DR: The auxin-inducible degron (AID) system allowed rapid and reversible degradation of target proteins in response to auxin and enabled us to generate efficient conditional mutants of essential proteins in yeast as well as cell lines derived from chicken, mouse, hamster, monkey and human cells, thus offering a powerful tool to control protein expression and study protein function.
