Intracellular calcium-binding proteins: more sites than insights.

Abstract

Calcium ions as biological regulators exert their effects in part via interaction with a wide variety of intracellular calcium-binding proteins. One class of these proteins shares a common calcium-binding motif, the EF-hand. A consensus amino acid sequence for this motif has aided the identification of new members of this family of EF-hand proteins, which now has about 170 members. A few of these proteins are present in all cells, whereas the vast majority are expressed in a tissue-specific fashion. The physiological function of a few of these proteins is known to be achieved via a calcium-dependent interaction with other proteins, thereby regulating their activity. The elucidation of the interactions and functions of the majority of these proteins remains a challenging task for the coming years.
