1.5 angstrom X-ray structure of bovine Ca(2+)-S100B
Template:ABSTRACT PUBMED 20053360
Function
[S100B_BOVIN] Weakly binds calcium but binds zinc very tightly-distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites. Binds to and initiates the activation of STK38 by releasing autoinhibitory intramolecular interactions within the kinase. Interaction with AGER after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling. Could assist ATAD3A cytoplasmic processing, preventing aggregation and favoring mitochondrial localization (By similarity).[1]
About this Structure
3iqo is a 2 chain structure with sequence from Bos taurus. Full crystallographic information is available from OCA.
