EF-HANDS 3,4 FROM ALPHA-ACTININ / Z-REPEAT 7 FROM TITIN
Overview
The interaction between alpha-actinin and titin, two modular muscle proteins, is essential for sarcomere assembly. We have solved the solution structure of a complex between the calcium-insensitive C-terminal EF-hand domain of alpha-actinin-2 and the seventh Z-repeat of titin. The structure of the complex is in a semi-open conformation and closely resembles that of myosin light chains in their complexes with heavy chain IQ motifs. However, no IQ motif is present in the Z-repeat, suggesting that the semi-open conformation is a general structural solution for calcium-independent recognition of EF-hand domains.
About this Structure
1H8B is a Protein complex structure of sequences from Homo sapiens and Oryctolagus cuniculus. Full crystallographic information is available from OCA.
