Dimerization of Peptides by Calcium Ions: Investigation of a Calcium-Binding Motif

Table 1

Major calcium-binding proteins in the nervous system.

Present in most cell types, including neurons	Present in certain cell types in CNS
EF-hand family	EF-hand family
Calmodulin [30]; (ubiquitous calcium-dependent modulator of protein kinases and other enzymes)	Parvalbumin [31]; (in some neurons)
Calpains [32]; (calcium-dependent proteases)	Calbindin-D28K [33]; (in some neurons)
α-Actinin [34]	Calretinin [33]; (in some neurons)
Other families	Recoverin, visinin [35]; (in photoreceptors; regulating guanylyl cyclase)
Annexins [36]; (Ca^2+-phospholipid-binding proteins of unknown function, but implicated in exocytosis)	S100α and S100β [9, 36]; (in glia; effects on phosphorylation and neurite outgrowth)
Protein kinase C [37]
