Research Papers that Mention the Interaction
“It is likely that, under the specific experimental conditions of proteolysis in the presence of SDS , the negatively charged C-terminal region can be rigidified by binding a calcium ion , as shown before with intact alpha-syn.”
Conformational properties of the SDS-bound state of alpha-synuclein probed by limited proteolysis: unexpected rigidity of the acidic C-terminal tail.“The helical stability of the peptide in SDS micelles was increased by addition of calcium ions.”
“Insertion of charged amphiphiles in the sarcolemma as phospholipid analogues modulate interaction of Ca with the sarcolemma, e.g., anionic dodecylsulfate increases Ca bound to sarcolemmal vesicles by more than 80% and increases force development in rabbit papillary muscle by 100%.”
The role of calcium at the sarcolemma in the control of myocardial contractility.“Dephosphorylation of the phosphate binding sites … M to P. High levels of calcium (2 mM) inhibit phosphorylation of … P. Protein patterns obtained by sodium dodecyl sulfate gel electrophoresis of irradiated retina membranes show an increased incorporation of label from [… protein bands of 48 kDa, 68 kDa and 200 kDa.”
“All five calmodulins are similar to vertebrate calmodulin as judged by their activation of … phosphodiesterase, calcium-dependent interaction with troponin I and with chloropromazine, increased anode mobility on sodium dodecyl sulfate gels … calcium , cross-reactivity with anti-vertebrate calmodulin antibodies and … the presence of a single residue of trymethyllysine.”
“The purified protein from trichocysts is indistinguishable from that of whole cells; it … heat-stable, activates brain phosphodiesterase in a Ca++-dependent fashion, changes mobility on SDS polyacrylamide gels in … presence of Ca++ , contains 1 mol of trimethyllysine/17 kdaltons, and has the amino acid composition characteristic of calmodulins.”
“Sodium deoxycholate and Ca++ were found to stimulate both phospholipases A1 and A2, whereas sodium dodecylsulfate strongly inhibited both enzyme activities.”
“It is concluded that SDS in low concentrations acts to reduce the binding capacity for Ca of sites located at the level of both superficial portion of the membrane and T tubular membrane.”
“Some observations on the effect of sodium lauryl sulphate on the translocation of calcium in vivo and in vitro are reported.”
“The enzymatic activity was enhanced by Ca2+ and was strongly inhibited by Cu2+ and SDS.”
