WebNov 1, 2015 · Crk and Abi1 interact with Abl kinase with different itineraries: Proposed model by which Crk SH3N binds to the C-terminal PRD of Abl and leads to phospho Tyr 251 mediated Abl transactivation. In this partially open conformation model of Abl kinase, SH3 domain of Abi1-Iso2 competes with SH3N domain of Crk for binding to C-terminal … WebMay 23, 2011 · Prompted by observations that Y221F Crk is phosphorylated by Abl using in vitro kinase assays, we set out to identify additional tyrosine phosphorylation sites on Crk. As the PNAY motif in the RT loop of SH3C was essential for Crk-mediated Abl transactivation (Reichman et al., 2005), we focused on Y251 which was a part of the …

The fate of activated Abl is not known, but some studies ... WebThe ubiquitously expressed c-Abl tyrosine kinase localizes to the cytoplasm and nucleus. Nuclear c-Abl is activated by diverse genotoxic agents and induces apoptosis; however, the mechanisms that are responsible for nuclear targeting of c-Abl remain unclear. Here, we show that cytoplasmic c-Abl is targeted to the nucleus in the DNA damage response.
