Although major components in this pathway have been identified, the knowledge on how individual components cooperate to effectively transduce signals remains limited. Phase separation emerges as a biophysical principle in organizing signaling molecules into liquid-like condensates. Here, we report that phospholipase Cγ1 (PLCγ1) promotes phase separation of LAT, a key adaptor protein in the TCR pathway. PLCγ1 directly cross-links LAT through its two SH2 domains. PLCγ1 also protects LAT from dephosphorylation by the phosphatase CD45 and promotes LAT-dependent ERK activation and SLP76 phosphorylation. Intriguingly, a nonmonotonic effect of PLCγ1 on LAT clustering was discovered. Computer simulations, based on patchy particles, revealed how the cluster size is regulated by protein compositions. Together, these results define a critical function of PLCγ1 in promoting phase separation of the LAT complex and TCR signal transduction.","lang":"eng"}],"type":"journal_article","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","day":"30","month":"04","article_processing_charge":"No","pmid":1,"date_updated":"2021-11-25T15:33:08Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","short":"CC BY-NC-SA (4.0)","image":"/images/cc_by_nc_sa.png","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)"},"title":"PLCγ1 promotes phase separation of T cell signaling components","quality_controlled":"1","status":"public","oa_version":"None","date_created":"2021-11-25T15:21:30Z","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","publisher":"Rockefeller University Press","scopus_import":"1","citation":{"ieee":"L.
