Bone morphogenetic protein receptor signal transduction in human disease

Signal transduction by bone morphogenetic proteins.

Bone morphogenetic proteins (BMPs) are multifunctional cytokines, which are members of the transforming growth factor-beta (TGF-beta) superfamily. Activities of BMPs are extracellularly regulated by BMP-binding proteins, Noggin and Chordin. BMPs bind to two different types of serine-threonine kinase receptors, type I and type II. Two BMP type I receptors and a BMP type II receptor have been ide...

Signal transduction and biological functions of bone morphogenetic proteins.

Bone morphogenetic proteins (BMPs) are multi-functional growth factors and belong to the transforming growth factor beta (TGFbeta) superfamily. The roles of BMPs in embryonic development and cellular functions in postnatal animals have been extensively studied in recent years. Signal transduction studies have revealed that Smad1 and 5 are the immediate downstream molecules of BMP receptor and p...

Signal Transduction and Human Disease

TrkC binds to the bone morphogenetic protein type II receptor to suppress bone morphogenetic protein signaling.

TrkC, a member of the tropomyosin-related kinase (Trk) family of neurotrophin receptors, is implicated in the growth and survival of human cancer tissues. TrkC is also a potent oncoprotein expressed in tumors derived from multiple cell lineages, and functions as an active protein tyrosine kinase by neurotrophin-3 (NT-3). We previously reported that TrkC plays an essential role in tumor growth a...

Erythropoietin receptor signal transduction requires protein geranylgeranylation.

Erythropoietin (Epo) acts through the erythropoietin receptor, a member of the type-1 cytokine receptor family, to influence survival, proliferation, and differentiation of erythroid progenitors. Epo stimulation of factor-dependent 32D cells results in phosphorylation of many proteins, including Janus kinase (Jak) 2, signal transducer and activator of transcription (Stat) 5, and extracellular s...
