Regulation of the MST1 kinase by autophosphorylation, by the growth inhibitory proteins, RASSF1 and NORE1, and by Ras.
MST1 (mammalian Sterile20-like 1) and MST2 are closely related Class II GC (protein Ser/Thr) kinases that initiate apoptosis when transiently overexpressed in mammalian cells. In the present study, we show that recombinant MST1/2 undergo a robust autoactivation in vitro, mediated by an intramolecular autophosphorylation of a single site [MST1(Thr183)/MST2(Thr180)] on the activation loop of an M...
متن کاملMutation of conserved active-site threonine residues in creatine kinase affects autophosphorylation and enzyme kinetics.
Muscle-type creatine kinase (MM-CK) is a member of an isoenzyme family with key functions in cellular energetics. It has become a matter of debate whether the enzyme is autophosphorylated, as reported earlier [Hemmer, Furter-Graves, Frank, Wallimann and Furter (1995) Biochim. Biophys. Acta 1251, 81-90], or exclusively nucleotidylated. In the present paper, we demonstrate unambiguously that CK i...

15 صفحه اولRegulation of membrane turnover by ras proteins.
Because ras oncogenes mediate abnormal cellular growth, ras proteins have been presumed to play a role primarily in growth control. The biological function of ras proteins may, however, prove to be much more diverse: ras proteins may be involved in cellular functions that control endocytosis and/or exocytosis.
متن کاملRegulation of RAS oncogenicity by acetylation.
Members of the RAS small GTPase family regulate cellular responses to extracellular stimuli by mediating the flux through downstream signal transduction cascades. RAS activity is strongly dependent on its subcellular localization and its nucleotide-binding status, both of which are modulated by posttranslational modification. We have determined that RAS is posttranslationally acetylated on lysi...
