Both, BCR and ROR1 are therapeutic targets in these diseases and the understanding of their mutual cross talk is thus of direct therapeutic relevance. In this study we analyzed the role of Lyn, a kinase from the Src family participating in BCR signaling, as a mediator of the BCR-ROR1 crosstalk. We confirm the functional interaction between Lyn and ROR1 and demonstrate that Lyn kinase efficiently phosphorylates ROR1 in its kinase domain and aids the recruitment of the E3 ligase c-CBL. We show that ROR1 surface dynamics in migrating primary CLL cells as well as chemotactic properties of CLL cells were inhibited by Lyn inhibitor dasatinib. Our data establish Lyn-mediated phosphorylation of ROR1 as a point of crosstalk between BCR and ROR1 signaling pathways.<\/jats:p>","DOI":"10.3389\/fcell.2022.838871","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T00:13:08Z","timestamp":1646007188000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Lyn Phosphorylates and Controls ROR1 Surface Dynamics During Chemotaxis of CLL Cells"],"prefix":"10.3389","volume":"10","author":[{"given":"Zankruti","family":"Dave","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"Vond\u00e1lov\u00e1 Blan\u00e1\u0159ov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0160t\u011bp\u00e1n","family":"\u010cada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavl\u00edna","family":"Janovsk\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikod\u00e9m","family":"Zezula","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"B\u011bhal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kate\u0159ina","family":"Han\u00e1kov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sri Ranjani","family":"Ganji","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavel","family":"Krejci","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krist\u00edna","family":"G\u00f6m\u00f6ryov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Peschelov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal","family":"\u0160m\u00edda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zbyn\u011bk","family":"Zdr\u00e1hal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0160\u00e1rka","family":"Pavlov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Kota\u0161kov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0160\u00e1rka","family":"Posp\u00ed\u0161ilov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V\u00edt\u011bzslav","family":"Bryja","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,2,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e1873","DOI":"10.1371\/journal.pone.0001873","article-title":"The Deleted in Brachydactyly B Domain of ROR2 Is Required for Receptor Activation by Recruitment of Src","volume":"3","author":"Akbarzadeh","year":"2008","journal-title":"PLoS One."},{"key":"B2","doi-asserted-by":"publisher","first-page":"161","DOI":"10.1007\/s004270100140","article-title":"Expression of the Ror1 and Ror2 Receptor Tyrosine Kinase Genes during Mouse Development","volume":"211","author":"Al-Shawi","year":"2001","journal-title":"Development Genes Evol."},{"key":"B3","doi-asserted-by":"publisher","first-page":"17","DOI":"10.1002\/hon.948","article-title":"ROR1 Expression Is Not a Unique Marker of CLL","volume":"29","author":"Barna","year":"2011","journal-title":"Hematol.
