"These marker proteins are listed in Table S-6 and include for instance calmodulin-1, MARCS, and the peptidyl-prolyl cis-trans isomerase FKBP9, which bind calcium; proteins with chaperone function (CH60, HSPB1, PRS4, and TCPA); components of the nuclear lamina (LMNA, LMNB1), as well as an interferon-induced GTP-binding protein (MX1); and vimentin, a class III intermediate filament."
"Calmodulin is the best studied and prototypical example of the e-f-hand family of ca2+-sensing proteins. In the event of a transient rise in Ca2+, the Ca2+ ion is coordinated in each Ca2+-binding loop of Ca2+CaM by seven, primarily carboxylate, ligands. The binding of Ca2+ leads to substantial alterations in the interhelical angles within the EF hands in each domain and dramatically changes the two domains of CaM to produce more open conformations"
