** 2012 REQUEST FOR PROPOSALS **
As of August 1, 2012, the TCNP of Lysine Modification is soliciting proposals for "Midi-Driving Biological Projects" (Midi-DBPs) for our Center's Core 2. Midi-DBPs are intended to fund pilot projects - ideally done within the TCNP itself - that will enable recipients, possibly together with their TCNP collaborators, to apply for larger scale funding of novel applications of TCNP technologies. Small-scale funding is available for 6-7 mini-DBPs between August 1, 2012 and July 31, 2013. For more information, please read the RFP or contact Dr. Jef Boeke by phone or email.

Our TCNP Mourns the Loss of Our Colleague, Professor Robert "Bob" J. Cotter
**November 13, 2012** We learned this morning, much to our shock, that our well-loved colleague, Bob Cotter, passed away during the night. Dr. Cotter was a world-reknowned and much honored pioneer in the field of mass spectrometry. His loss will be deeply felt by family, friends and colleagues here at Johns Hopkins, as well as by the greater scientific community. We will post more details as they become available.
Our TCNP Mourns the Loss of Former Colleague Yu-yi Lin
**September 6, 2012** A Memorial Service to celebrate the life of Dr. Yu-yi Lin will be held on September 6, 2012, at 4:00 PM, in the Sheik Zayed Tower Interfaith Chapel at Johns Hopkins University Hospital. If you have a photo or other memento that you would like to share, or if you would like to speak at the Memorial, please send it to us at: firstname.lastname@example.org. There will also be an opportunity at the Memorial to leave a written message for Yu-yi and his family.

**August 8, 2012** It is with great sadness that we acknowledge and grieve the untimely death of our friend and former colleague Dr. Yu-yi Lin. Yu-yi was a Johns Hopkins BCMB graduate student and post-doctoral fellow in Jef Boeke’s lab. He was an outstanding and very productive scientist, who pioneered much of this TCNP’s work on genetic and protein microarray approaches to defining lysine acetyltransferase and deacetylase networks. While at JHU, Yu-yi won a number of awards for his work, including the David Israel Macht Award for young investigators in 2009, for using a protein acetylation microarray to discover that NuA4 regulates cell metabolism and aging. In the same year, Yu-yi set up his own lab at the National Taiwan University College of Medicine in Taipei, where he focused on lysine modification pathways in human cells. Yu-yi leaves behind his wife, Jin-ying Lu, and three young daughters, as well as a multitude of friends and family who miss him very much.

Glucose and weight control in mice with a designed ghrelin O-acyltransferase inhibitor. Science. 330, 1689-1692. PubMed Link
This paper describes the rational design, synthesis and biological properties of a bisubstrate inhibitor of the ghrelin O-acyltransferase (GOAT) enzyme. Ghrelin is a peptide hormone that promotes weight gain in vertebrates and its bioactivity requires GOAT-dependent octanylation at Ser3. Inhibition of GOAT in vivo, which presumably alters ghrelin activity, improves glucose tolerance and reduces weight gain in wild-type mice. The work suggests that GOAT represents a new clinical target for the treatment of human metabolic disease.

A proteome-wide search for nonhistone substrates of the essential nucleosome acetyltransferase of H4 (NuA4) complex was carried out using yeast proteome microarrays. Among newly identified substrates are many cytoplasmic metabolic enzymes known to respond to extracellular nutrient sources and/or intracellular energy status. Acetylation of phosphoenolpyruvate carboxykinase (Pck1), the rate-limiting enzyme in gluconeogenesis, turns out to be crucial for its enzymatic activity both in yeast and in human hepatocellular carcinoma (HepG2) cells. This indicates an unexpected extra-nuclear function of NuA4 in regulating metabolism in addition to its well-known roles in regulating chromatin-related processes, and suggests that the two processes are somehow coupled. Furthermore, deacetylation of Pck1 by the histone deacetylase Sir2 suggests reveals a connection between gluconeogenesis and chronological life span in yeast.

To probe nucleosome function in vivo, Dai and Hyland constructed a yeast library of 486 histone H3 and H4 mutants. The library includes both systematic substitutions and tail deletion alleles, and the design features enable analysis of each mutant either episomally or at the endogenous locus. Moreover, each mutant is tagged with unique molecular barcodes to facilitate phenotypic analysis of complex pools of histone mutants using repurposed microarrays previously designed for analyzing yeast knockout collections. Such phenotypic analysis mapped nucleosome surfaces required for transcriptional silencing, response to genome stress, fitness in a chemostat, and NHEJ. This collection of histone mutants will enable researchers to probe nucleosomal function in response to myriads of growth conditions or genetic alterations and should elucidate cis- and trans-acting signals for lysine modification within the nucleosome. Construction of more H3 and H4 mutants, as well as histone H2A and H2B mutants are underway! A database that documents these mutations and their associated phenotypes can be found here. This mutant collection will soon be available through Open Biosystems!

The authors used a combination of yeast proteome chip assays, genetic screening, and in vitro/in vivo biochemical analyses to identify and characterize eight novel in vivo substrates of the yeast ubiquitylating enzyme Rsp5, a homolog of the human ubiquitin-ligating enzyme Nedd4. This work illustrates how proteome chips can be used to define probable in vivo substrates of lysine modifying enzymes.

Global patterns of synthetic lethal genetic interactions defined 16 functional modules within the genetic network governing DNA integrity in budding yeast. Modules or genes involved in DNA replication, DNA replication checkpoint signaling, and oxidative stress response were shown to be the major guardians against intrinsic DNA damage. In addition, new regulators of mitotic DNA replication and genomic stability were identified. This work provided rich data for further study of genome integrity and validated the development and use of genetic approaches to study the networks, pathways and dynamics of lysine modification.
