How does a regulatory protein know where to bind to modulate insulin production?
Some proteins in the body ensure that genes are turned on and off at the correct times. Understanding where speckle-type POZ protein (SPOP) binds may help researchers predict what predisposes individuals to develop diabetes and clarify how SPOP regulates other important proteins. In a recent study, a team of researchers from Penn State and St. Jude Children’s Research Hospital imaged the proteins and determined just how this important interaction occurs.

'Anti-antibiotic' allows for use of antibiotics without driving resistance
An inexpensive, FDA-approved drug — cholestyramine — taken in conjunction with an antibiotic prevents the antibiotic from driving antimicrobial resistance, according to new research by scientists at Penn State and the University of Michigan. The team’s findings appear today (Dec. 1) in the journal eLife.
