Emerald and UCB had initiated their collaboration partnership in January 2009.
Under the agreement, both the companies have identiified a series of small molecules and have solved high-resolution X-ray crystallographic structures of multiple targets.
Emerald COO Alex Burgin said in this collaborative effort, they have identified multiple modulators of protein structure and function.
Emerald CEO Lance Stewart said the expansion of UCB collaboration is an important demonstration of the confidence that UCB has in the Emerald team, and is a clear validation of fragment-based X-ray structure technology, especially when applied to challenging targets.
