摘要: Calcium (Ca2+) is a ubiquitous second messenger in all eukaryotes. An outstanding question is how this cation serves as a messenger for numerous signals and confers specific cellular responses. Recent studies have established a concept termed 'Ca2+ signature'that specifies Ca2+ changes triggered by each signal. How do cells recognize these signatures (codes) and translate them into the correct cellular responses? The initial step in this 'decoding'process involves sensor proteins that bind Ca2+ and activate the downstream …
