| Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n CRACR2B (also known as CRAC regulator 2A and encoded by EFCAB4B) is a calcium‐binding EF‐hand protein that plays a pivotal role in the regulation of store‐operated calcium entry (SOCE) in immune cells. In response to endoplasmic reticulum Ca²⁺ store depletion, CRACR2B physically interacts with both Orai1 and STIM1 to form a ternary complex. This interaction promotes the clustering of Orai1 and STIM1, thereby facilitating the opening of CRAC channels and enabling Ca²⁺ influx. Importantly, the CRACR2B–Orai1–STIM1 complex is sensitive to intracellular Ca²⁺ levels; as Ca²⁺ concentrations rise, the complex dissociates, providing a feedback mechanism that prevents excessive calcium entry. Mutations affecting its EF‐hand domain can lead to abnormal channel activity, elevated cytosolic Ca²⁺ levels, and ultimately cell death. These findings underscore the role of CRACR2B as an essential Ca²⁺ sensor and regulator in T cells and likely other vertebrate cells."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Sonal Srikanth, Hea-Jin Jung, Kyun-Do Kim, et al.
