Phosphorylation of Dok1 by Abl family kinases inhibits CrkI transforming activity

The Crk SH2/SH3 adaptor and the Abl nonreceptor tyrosine kinase were first identified as oncoproteins, and both can induce tumorigenesis when overexpressed or mutationally activated. We previously reported the...

Phosphorylation of Crk on tyrosine 251 in the RT loop of the SH3C domain promotes Abl kinase transactivation

Here, we report the identification and characterization of a novel tyrosine phosphorylation site in the carboxy-terminal Src Homology 3 (SH3) (SH3C) domain of the Crk adaptor protein. Y251 is located in the hi...

Effects of Majorana Edge Fermions on Dynamical Spin Susceptibility in Topological Superfluid ³He-B

The low-energy quasiparticle structures in the vicinity of the specular surface of the superfluid ³He-B are theoretically investigated, based on the Bogoliubov-de Gennes (BdG) framework. A non-trivial topological...

Proteins that bind the Src homology 3 domain of CrkI have distinct roles in Crk transformation

The v-Crk oncogene product consists of two protein interaction modules, a Src homology 2 (SH2) domain and a Src homology 3 (SH3) domain. Overexpression of CrkI, the cellular homolog of v-Crk, transforms mouse ...
