Research Abstract |
To understand molecular signaling involved in neuromuscular synaptogenesis, hematopoiesis, and related disorders, we focused on the Dok-family of adaptor proteins. Our findings together revealed that the cytoplasmic protein Dok-7 directly interacts with the receptor tyrosine kinase MuSK and activates it to form neuromuscular synapses. We also revealed that autoantibodies to Lrp4, a MuSK's coreceptor, in patients with myasthenia gravis, and that Dok-1/2/3 suppress histiocytic sarcoma.
