S100A13 (S100 calcium binding protein A13)

Calcium-binding S100 protein expression in pterygium

PURPOSE Pterygium is an ocular surface disease of unknown etiology associated with epithelial and fibrovascular outgrowth from the conjunctiva onto the cornea. S100 proteins are calcium-activated signaling proteins that interact with other proteins to modulate biological functions such as cell migration, proliferation, and differentiation. The aim of this study was to investigate the presence o...

S100A9 (S100 calcium binding protein A9)

Note S100A9 belongs to the S100/calgranulin family of small non-ubiquitous cytoplasmic Ca-binding proteins of EF-hand type. The proteins were referred to "S100" because of their solubility in saturated ammonium sulphate solution. Sixteen of 21 members are localised in a cluster on human chromosome 1q21. The clustered organization of these S100 genes is conserved during evolution (Ridinger et al...

Binding of pEL98 protein, an S100-related calcium-binding protein, to nonmuscle tropomyosin

The cDNA coding for mouse fibroblast tropomyosin isoform 2 (TM2) was placed into a bacterial expression vector to produce a fusion protein containing glutathione-S-transferase (GST) and TM2 (GST/TM2). Glutathione-Sepharose beads bearing GST/TM2 were incubated with [35S]methionine-labeled NIH 3T3 cell extracts and the materials bound to the fusion proteins were analyzed to identify proteins that...

S100 Calcium Binding Proteins and Ion Channels

S100 Ca(2+)-binding proteins have been associated with a multitude of intracellular Ca(2+)-dependent functions including regulation of the cell cycle, cell differentiation, cell motility and apoptosis, modulation of membrane-cytoskeletal interactions, transduction of intracellular Ca(2+) signals, and in mediating learning and memory. S100 proteins are fine tuned to read the intracellular free C...
