Histone H2B monoubiquitylation (H2Bub1) has central functions in multiple DNA-templated processes, including gene transcription, DNA repair, and replication. H2Bub1 also is required for the trans-histone regulation of H3K4 and H3K79 methylation. Although previous studies have elucidated the basic mechanisms that establish and remove H2Bub1, we have only an incomplete understanding of how H2Bub1 is regulated. We report here that the histone H4 basic patch regulates H2Bub1. Yeast cells with arginine-to-alanine mutations in the H4 basic patch (H42RA) exhibited a significant loss of global H2Bub1. H42RA mutant yeast strains also displayed chemotoxin sensitivities similar to, but less severe than, strains containing a complete loss of H2Bub1. We found that the H4 basic patch regulates H2Bub1 levels independently of interactions with chromatin remodelers and separately from its regulation of H3K79 methylation. To measure H2B ubiquitylation and deubiquitination kinetics in vivo, we used a rapid and reversible optogenetic tool, the light-inducible nuclear exporter, to control the subcellular location of the H2Bub1 E3 ligase, Bre1. The ability of Bre1 to ubiquitylate H2B was unaffected in the H42RA mutant. In contrast, H2Bub1 deubiquitination by SAGA-associated Ubp8, but not by Ubp10, increased in the H42RA mutant. Consistent with a function for the H4 basic patch in regulating SAGA deubiquitinase activity, we also detected increased SAGA-mediated histone acetylation in H4 basic patch mutants. Our findings uncover that the H4 basic patch has a regulatory function in SAGA-mediated histone modifications.

The immigrant population in the Kansas City region has grown rapidly over the past 25 years, contributing to overall population growth in the area. This fact sheet describes immigrants in the metro area, examining their origins, industries of employment, income and poverty levels, English proficiency, educational attainment, and more.

Thailand has become a key destination for migrant workers, primarily from Myanmar, Cambodia, and Laos. Many lack authorization, however, and as their numbers have grown, so has the government's intent in regulating their movement—sometimes provoking unintended results. This article explores recent patterns in labor migration to Thailand and examines the likely impacts of a 2017 decree criminalizing illegal employment.

As the final phase of preparations for the historic adoption of a Global Compact for Safe, Orderly, and Regular Migration approaches, this webinar explores two central objectives of the compact: enhancing the availability and flexibility of pathways for regular migration, and investing in skills development.

Authoritarian states have long attempted to restrict citizens’ movement. But what happens when their reach extends beyond their borders? The October 2018 assassination of Saudi journalist Jamal Khashoggi brought into sharp relief the long arm of these regimes in reaching citizens abroad. This phenomenon, “transnational authoritarianism,” further shows that the relationship between migration and authoritarianism is becoming more complex.

Nearly 50,000 asylum seekers have entered Canada irregularly via land crossing from the United States since spring 2017—contributing to a doubling in the overall number of asylum requests seen in 2016. Based on interviews with asylum claimants, this article analyzes their motivations for making the journey and the political implications of rising irregular migration to Canada.

Given diverging demographics, rising educational attainment and wide variation in economic opportunities, countries in the Association of Southeast Asian Nations are poised to see an expansion of both the demand for and supply of skilled migrants willing and able to move. The convergence of these megatrends represents unique opportunities for human-capital development and brain circulation, as this report explores.

Marking the release of an MPI report, speakers on this webinar present an overview of regional immigration enforcement trends, including U.S. and Mexican apprehensions and deportations of both children and adults, along with a demographic, socioeconomic, and criminal profile of child and adult deportees.

OBJECTIVE

To determine if temporal glucose profiles differed between 1) women who were randomized to real-time continuous glucose monitoring (RT-CGM) or self-monitored blood glucose (SMBG), 2) women who used insulin pumps or multiple daily insulin injections (MDIs), and 3) women whose infants were born large for gestational age (LGA) or not, by assessing CGM data obtained from the Continuous Glucose Monitoring in Women With Type 1 Diabetes in Pregnancy Trial (CONCEPTT).

With the growing urbanization and consolidation of Nicaraguan immigrants in sectors such as construction and domestic service, Costa Rica has shifted its focus from immigration enforcement to integration. Tension has emerged between the government and private sector as a new mechanism for regularizing unauthorized immigrant workers has failed to gain traction.

European policymakers are fixated on reform of the Dublin Regulation, the contentious rules that carve up responsibility for asylum claims between EU states. They see it not only as a long-term prophylactic against future fluctuations in irregular migration, but as a marker of the success or failure of solidarity in Europe overall. Yet rather than doggedly working to salvage Dublin, policymakers need to stop and consider why they regard it as so integral to European cooperation, as this commentary explores.
