WebMechanistically, PRRSV Nsp2 retains STING at the ER by increasing the level of Ca 2+ sensor stromal interaction molecule 1 (STIM1) protein. Functional analysis reveals that PRRSV Nsp2 deubiquitinates STIM1 by virtue of its papain-like protease 2 … Stromal interaction molecule 1 is a protein that in humans is encoded by the STIM1 gene. STIM1 has a single transmembrane domain, and is localized to the endoplasmic reticulum, and to a lesser extent to the plasma membrane. Even though the protein has been identified earlier, its function was unknown until recently. In 2005, it was discovered that STIM1 functions as a calcium se… class b cdl with air brake endorsement

WebNov 15, 2024 · STIM1 (stromal interaction molecule 1) is a single-pass transmembrane protein that acts as a luminal calcium (Ca 2+) sensor of the endoplasmic reticulum (ER). 1 … WebGOK; SIM; STIM 1; STIM1; STIM-1; Stim1 stromal interaction molecule 1; STIM1_HUMAN; STIM1L; Stromal interaction molecule 1. Background: Plays a role in mediating store-operated Ca(2+) entry (SOCE), a Ca(2+) influx following depletion of intracellular Ca(2+) stores. Acts as Ca(2+) sensor in the endoplasmic reticulum via its EF-hand domain. Stromal interaction molecule 1 (STIM1) resides in the endoplasmic reticulum (ER) membrane and senses luminal calcium (Ca2+) concentration. STIM1 activation involves a large‐scale conformational transition that exposes a STIM1 domain termed “CAD/SOAR”, ‐ which is required for activation of the calcium channel Orai. Under resting … class b chainsaw chaps
