The 14 A resolution structure of the 2.3 MDa Ca$^2+$ release channel
(also known as RyR1) was determined by electron cryomicroscopy and
single particle reconstruction. This structure was produced using
collected data used for our previous published structures at 22-30
A resolution, but now taking advantage of recent algorithmic improvements
in the EMAN software suite. This improved map clearly exhibits more
structural detail and allows better defined docking of computationally
predicted structural domain folds. Using sequence-based fold recognition,
the N-terminal region of RyR1, residues 216-572, was predicted to
have significant structural similarity with the IP3-binding core
region of the type 1 IP3R. This putative structure was computationally
localized to the clamp-shaped region of RyR1, which has been implicated
to have a regulatory role in the channel activity.
