This second phase requires signaling by a Src-family kinase such as Lck. These data point out two aspects of the initial stage of TCR signaling that have not yet been clearly resolved. Firstly, how and by which Src-family kinase, is the initial phosphorylation of CD3ζ accomplished, given that the Lck associated with the co-receptors (CD4 or CD8) is not yet available. Secondly, what is the mechanism by which the co-receptor is brought close to the bound TCR before the co-receptor binds to MHCp? eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ Atribución 4.0 Internacional Initiation of TCR Phosphorylation and Signal Transduction info:eu-repo/semantics/article
