CRAC channel pathway

Extracted Explainers

What the tool is doing

The CRAC channel pathway mediates Ca2+ entry into cells through STIM/Orai coupling. The abstract presents it as a key signaling route relevant to immune-cell function.

Source 1DOI PubMed

Resources required

The pathway depends on the coupling of STIM in the ER membrane and Orai in the plasma membrane, as described in the abstract.

Source 1DOI PubMed

What problem it solves

In this review context, it is the signaling pathway that synthetic-biology tools aim to control precisely.

Source 1DOI PubMed

What it does not solve

The abstract does not describe this pathway itself as a standalone engineered tool or as sufficient to specify a particular implementation.

Source 1DOI PubMed

Alternatives

No alternative calcium-entry pathways or synthetic-control frameworks are explicitly contrasted in the abstract.

Evidence Snippets

This also applies to a main Ca2+ entry pathway into the cell, the so-called Ca2+ release-activated Ca2+ (CRAC) channel.

Claim 1functional rolesupports2024Source 1DOI PubMed

Ca2+ entry established via STIM/Orai coupling is essential for immune cell functions including cytokine release, proliferation, and cytotoxicity.

Claim 2mechanismsupports2024Source 1DOI PubMed

Receptor-ligand binding at the cell membrane initiates a signaling cascade that triggers coupling of STIM and Orai, the two key molecular components of the CRAC channel.
