WebSTAT3 is activated by phosphorylation on tyrosine 705 by c-Jun N-terminal kinases (JNKs), cytokine receptor-associated kinases, nonreceptor tyrosine kinases, and growth factor receptor tyrosine kinases, in response to growth factors and cytokines. Phosphorylation of STAT3 is important for dimer formation and gene expression. WebResults reveal that ACBD3 and Rab4A play a key role in regulating KDEL receptor trafficking to the cell surface and that KDELR trafficking from the Golgi to the PM is independent of PKA- and Src kinase-mediated mechanisms. KDEL receptor-1 maintains homeostasis in the early secretory pathway by capturing and retrieving ER chaperones to the ER during heavy …
