Lysine acetylation is a widespread post-translational modification regulating various biological processes. To characterize cellular functions of the human lysine acetyltransferases KAT2A (GCN5) and KAT2B (PCAF), we determined their acetylome by shotgun pr ...
Leukemias expressing constitutively activated mutants of ABL1 tyrosine kinase (BCR-ABL1, TEL-ABL1, NUP214-ABL1) usually contain at least 1 normal ABL1 allele. Because oncogenic and normal ABL1 kinases may exert opposite effects on cell behavior, we examine ...
Bcr-Abl is a constitutively active kinase that causes chronic myelogenous leukemia. We have shown that a tandem fusion of two designed binding proteins, termed monobodies, directed to the interaction interface between the Src homology 2 (SH2) and kinase do ...

In this issue of Blood, Appelmann et al provide evidence for prolonged survival and prevention of resistance in a mouse model of Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) by combined targeting of the BCR-ABL kinase and Janus ...
Polo-like kinase 1 (PLK1) is a serine/threonine kinase that plays multiple and essential roles during the cell division cycle. Its inhibition in cultured cells leads to severe mitotic aberrancies and cell death. Whereas previous reports suggested that Plk1 ...
The Notch signaling pathway is a key regulator of cell fate decisions in embryonic development and in adult tissue homeostasis. Mounting evidence suggests that Notch signaling is frequently deregulated in human neoplasms, where depending upon the cellular ...
A number of structural factors modulate the activity of Abelson (Abl) tyrosine kinase, whose deregulation is often related to oncogenic processes. First, only the open conformation of the Abl kinase domain's activation loop (A-loop) favors ATP binding to t ...
The JAK/STAT pathway is a key signaling pathway in the regulation of development and immunity in metazoans. In contrast to the multiple combinatorial JAK/STAT pathways in mammals, only one canonical JAK/STAT pathway exists in Drosophila. It is activated by ...
Due to their central role in normal cellular physiology, the activity of protein kinases is tightly regulated and their aberrant activation can lead to cancer. Chronic myelogenous leukemia (CML) is a blood cancer characterized by unregulated growth of myel ...
Capillary Morphogenesis Gene 2 (CMG2) is a 55kDa single-pass transmembrane protein best described as the main Anthrax Toxin Receptor. However, CMG2 physiological role remains elusive and understanding better its in vivo function was the main objective of m ...
