The nonreceptor tyrosine kinase c-Abl is tightly regulated in vivo, but the mechanisms that normally repress its activity are not well understood. We find that a construct encoding the first two Src h...
We show here the identification of Duet, a novel molecule bearing serine/threonine kinase, Dbl-Homology (DH), and Pleckstrin-Homology (PH) domains. The kinase domain of Duet shows a homology to that o...
A homology stratification is a filtered space with local homology groups constant on strata. Despite being used by Goresky and MacPherson [3] in their proof of topological invariance of intersection h...
Bovine lens alpha A- and alpha B-crystallin polypeptides show extensive sequence homology with each other, but apparently none with beta Bp- and gamma 2-crystallin. Despite only 30% sequence homology,...
Homocracy, a term referring to shared regulatory gene expression patterns between organs in different animals, was introduced recently in order to prevent inappropriate inference of organ homology bas...
DNA interstrand cross-links (ICLs) are complex DNA lesions generated by bifunctional alkylating agents, a class of compounds extensively used in cancer chemotherapy. Formation of an ICL covalently lin...
Vav and Sos1 are Dbl family guanine nucleotide exchange factors, which activate Rho family GTPases in response to phosphatidylinositol 3-kinase products. A pleckstrin homology domain adjacent to the c...
When researchers build high-quality models of protein structure from sequence homology, it is today common to use several alternative target-template alignments. Several methods can, at least in theor...
