An atomic model of the 3744-residue Tra1 protein reveals multiple transcription activator binding sites, its integration within the SAGA chromatin coactivator complex, and a striking similarity to DNA-repair factor DNA-PKcs.
Kif26b, a new component of the evolutionarily conserved Wnt5a-Ror signaling pathway, is controlled by regulated proteolysis and plays crucial roles in mediating vertebrate embryonic tissue morphogenesis.
An aspartyl protease is essential for the lytic cycle of Toxoplasma gondii and is involved in the maturation of proteins critical for invasion and egress, and it can be targeted selectively with an ethylamine scaffold based peptidomimetic inhibitor.
The maize CLAVATA receptor, FEA2, functions in the perception of two different ligands, and remarkably that signaling from these different inputs is differentiated by the receptor interacting with two different downstream components.
The clinically approved HER2 inhibitor lapatinib causes HER2 and HER3 kinase domains to dimerise in a non-canonical, symmetric orientation, providing a platform for oligomerisation and predisposing to receptor-driven cell proliferation.
