LiCAMs
Also known as: light-sensitive calcium actuators and modulators
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
In this review, we examine the principles behind the design and engineering of light-sensitive calcium actuators and modulators (designated LiCAMs) and the applications of representative LiCAMs in remote and noninvasive control of Ca2+-modulated physiological processes both in vitro and in vivo.

These approaches require optogenetic light stimulation and engineered light-sensitive calcium control systems. The abstract also highlights non-opsin-based designs, especially CRAC-channel-derived systems.; requires optogenetic light-based control; review emphasizes representative tools rather than a single standardized construct
Needs compatible illumination hardware and optical access. Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
