Growth factor signaling pathways are tightly regulated by phosphorylation and include many important kinase targets of interest for drug discovery. Small molecule inhibitors the bone morphogenetic protein (BMP) receptor ALK2 (ACVR1) needed urgently to treat progressively debilitating musculoskeletal disease fibrodysplasia ossificans progressiva (FOP). Dorsomorphin analogues, first identified in zebrafish, remain only BMP inhibitor chemotype reported date. By screening an assay panel 250...

Bone morphogenetic protein (BMP) receptor kinases are tightly regulated to control development and tissue homeostasis. Mutant kinase domains escape regulation leading severely degenerative diseases represent an important therapeutic target. Fibrodysplasia ossificans progressiva (FOP) is a rare but devastating disorder of extraskeletal bone formation. FOP-associated mutations in the BMP ALK2 reduce binding inhibitor FKBP12 promote leaky signaling absence ligand. To establish structural...

Janus kinases (JAKs) are a family of cytoplasmatic tyrosine that attractive targets for the development anti-inflammatory drugs given their roles in cytokine signaling. One question regarding JAKs and inhibitors remains under intensive debate is whether JAK should be isoform selective. Since JAK3 functions restricted to immune cells, an isoform-selective inhibitor could especially valuable achieve clinically more useful precise effects. However, high degree structural conservation makes...

Although the conserved AAA ATPase and bromodomain factor, ATAD2, has been described as a transcriptional co-activator upregulated in many cancers, its function remains poorly understood. Here, using combination of ChIP-seq, ChIP-proteomics, RNA-seq experiments embryonic stem cells where Atad2 is normally highly expressed, we found that an abundant nucleosome-bound protein present on active genes, associated with chromatin remodelling, DNA replication, repair factors. A structural analysis...
