== Publication Abstract from PubMed == | |||
The S100 family, with about 20 members in humans, is composed of EF-hand calcium-regulated proteins and is linked to a range of serious human diseases, including cancer and autoimmune and neurological disorders. The oldest S100 family members are found in teleosts (bony fish). The zebrafish, Danio rerio, was suggested as a promising model system for in vivo studies on S100 family functions, and we chose to investigate zebrafish S100Z as the closest homologue of the metastasis-promoting human S100A4. Here, we report the first crystal structure of an S100 protein from this organism, the calcium-bound state of S100Z to 2.03 A resolution. Crystal packing suggests higher-order oligomerisation of S100Z dimers, with a tetramerisation interface very similar to, but even more extensive than, that reported for S100A4. The interactions are primarily through the C-terminal alphaIV helices from adjacent dimers in an antiparallel orientation. Structural comparisons between known S100 multimeric assemblies together with analysis of calcium-driven changes to the dimerisation cores suggest a mechanism for calcium-promoted oligomerisation of S100 proteins. | |||
