Structure of the MRAS-SHOC2-PP1C phosphatase complex.

Publication Type: Academic Journal

Source(s): Nature [Nature] 2022 Sep; Vol. 609 (7926), pp. 416-423. Date of Electronic Publication: 2022 Jul 13.

Abstract: RAS-MAPK signalling is fundamental for cell proliferation and is altered in most human cancers 1-3 . However, our mechanistic understanding of how RAS signals through RAF is still incomplete. Although studies revealed snapshots for autoinhibited and ac...

Structural Analysis and Development of Notum Fragment Screening Hits.

Publication Type: Academic Journal

Source(s): ACS chemical neuroscience [ACS Chem Neurosci] 2022 Jul 06; Vol. 13 (13), pp. 2060-2077. Date of Electronic Publication: 2022 Jun 22.

Abstract: The Wnt signaling suppressor Notum is a promising target for osteoporosis, Alzheimer's disease, and colorectal cancers. To develop novel Notum inhibitors, we used an X-ray crystallographic fragment screen with the Diamond-SGC Poised Library (DSPL) and ...

Xtrapol8 enables automatic elucidation of low-occupancy intermediate-states in crystallographic studies.

Publication Type: Academic Journal

Source(s): Communications biology [Commun Biol] 2022 Jun 29; Vol. 5 (1), pp. 640. Date of Electronic Publication: 2022 Jun 29.

Abstract: Unstable states studied in kinetic, time-resolved and ligand-based crystallography are often characterized by a low occupancy, which hinders structure determination by conventional methods. To automatically extract structural information pertaining to ...

An isoindoline bridged [M(η 6 -arene) 2 ] + (M = Re, 99m Tc) ansa -arenophane and its dinuclear macrocycles with axial chirality.

Publication Type: Academic Journal

Source(s): Dalton transactions (Cambridge, England : 2003) [Dalton Trans] 2022 Jun 27; Vol. 51 (25), pp. 9591-9595. Date of Electronic Publication: 2022 Jun 27.

Abstract: This work presents a straightforward method for the preparation of an isoindoline bridged [M(arene) 2 ] + (M = Re, 99m Tc) ansa -[3]arenophane. This intramolecular formation of an ansa -complex is accompanied by the intermolecular formation of a pair o...
