Upcoming Events


UCSF ChimeraX

UCSF ChimeraX (or simply ChimeraX) is the next-generation molecular visualization program from the Resource for Biocomputing, Visualization, and Informatics (RBVI), following UCSF Chimera. ChimeraX can be downloaded free of charge for academic, government, nonprofit, and personal use. Commercial users, please see ChimeraX commercial licensing.

ChimeraX is developed with support from National Institutes of Health R01-GM129325.

Virtual Reality

ChimeraX virtual reality works with HTC Vive, Oculus Rift, and Samsung Odyssey systems (those supported by SteamVR). Any structures, maps, etc. that can be displayed in ChimeraX can be viewed in the headset and manipulated with the hand controllers. Icon toolbars visible in the headset allow changing the scene display or hand-controller button assignments with a single click. Besides rotation, translation, and zooming, useful functions include labeling, distance measurement, bond rotation, placing markers into a map, and changing map contour levels. Virtual-reality (VR) mode can be turned on and off with the vr command, and the meeting command allows multiple users to share a single session in VR.

CaM-CaMKI peptide

Calmodulin and Target Peptide

Calmodulin (CaM) acts as a calcium sensor. When its four Ca++ sites are fully occupied, it binds and modulates the activity of various downstream proteins, including CaM-dependent protein kinase I (CaMKI). Here, a complex between CaM and its target peptide from CaMKI (PDB 1mxe) is shown with cartoons, a transparent molecular surface, silhouette outlines, and light soft ambient occlusion. (If you prefer a less smudgy/rustic appearance, try using light gentle instead.) For image setup other than positioning, see the command file cam.cxc.
