Structural and functional insight into human O-GlcNAcase

March 27th, 2017 by Christian Roth

Nature Chemical Biology 13, 610 (2017). doi:10.1038/nchembio.2358

O-GlcNAc hydrolase (OGA) removes O-linked N-acetylglucosamine (O-GlcNAc) from a myriad of nucleocytoplasmic proteins. Through co-expression and assembly of OGA fragments, we determined the three-dimensional structure of human OGA, revealing an unusual helix-exchanged dimer that lays a structural foundation for an improved understanding of substrate recognition and regulation of OGA. Structures of OGA in complex with a series of inhibitors define a precise blueprint for the design of inhibitors that have clinical value.

Signaling: Spatial regulation of axonal cAMP

In early-stage developing neurons, the cAMP–PKA (protein kinase A) signaling pathway is strongly inhibited. This negative control is later removed, unleashing cAMP–PKA signaling, particularly in distal axonal parts, thus allowing for axonal growth.

Protein folding: Illuminating chaperone activity

Pharmacological chaperones are small drugs that stabilize a protein's fold and are being developed to treat diseases arising from protein misfolding. A mathematical framework to model their activity in cells enables insight into their mechanism and capacity to rescue protein foldedness.

Simultaneous quantification of protein order and disorder

Nature Chemical Biology 13, 339 (2017). doi:10.1038/nchembio.2331

Nuclear magnetic resonance spectroscopy is transforming our views of proteins by revealing how their structures and dynamics are closely intertwined to underlie their functions and interactions. Compelling representations of proteins as statistical ensembles are uncovering the presence and biological relevance of conformationally heterogeneous states, thus gradually making it possible to go beyond the dichotomy between order and disorder through more quantitative descriptions that span the continuum between them.
