The 1.5 A Crystal structure of Ca2+-bound S100A4
Structural highlights
FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedS100A4 takes part in control of tumour cell migration and contributes to metastatic spread in in vivo models. In the active dimeric Ca(2+)-bound state it interacts with multiple intracellular targets. Conversely, oligomeric forms of S100A4 are linked with the extracellular function of this protein. We report the 1.5A X-ray crystal structure of Ca(2+)-bound S100A4 and use it to identify the residues involved in target recognition and to derive a model of the oligomeric state. We applied stopped-flow analysis of tyrosine fluorescence to derive kinetics of S100A4 activation by Ca(2+) (k(on)=3.5 microM(-1)s(-1), k(off)=20s(-1)).
