Sin1, a regulatory subunit of TOR protein kinase, has an evolutionarily conserved domain that specifically binds and recruits substrate for phosphorylation, and may represent a potential target for anti-cancer drugs.

The Rag-family GTPases, known activators of TOR complex 1 (TORC1), also function as attenuator that prevents deregulated hyperactivation of TORC1 signaling.

Lin37 is essential for cell-cycle gene repression by the DREAM complex in cellular quiescence and a combined loss of Lin37 and Rb prevents cell-cycle exit in response to growth-limiting signals.

The H+ influx coupled to nutrient uptake and the plasma membrane H+-ATPase are central actors of the activation of target of rapamycin complex 1 (TORC1) in budding yeast Saccharomyces cerevisiae..

A conserved mitochondrial inner membrane complex called MICOS works together with the mitochondrial lipid cardiolipin and respiratory complexes to direct the position, copy number and stabilization of cristae structures for efficient respiration.

Biochemical approaches reveal that an epigenetic histone deacetylase complex called CoREST is slow to deacetylate histone H3 lysine-14 in nucleosomes, and this inhibits demethylation of histone H3 lysine-4 by the CoREST complex.

Targeting the CRL5 ubiquitin ligase complex in combination with CDK9 or MCL1 inhibition could combat innate and acquired resistance of cancer cells to MCL1-targeting therapeutics.

A new mechanism is uncovered by which the RNF168 ubiquitin ligase couples PALB2-dependent homologous recombination to H2A ubiquitylation to promote DNA repair and preserve genome integrity.

The E3 ubiquitin ligase activity of polycomb repressive complex 1 is stimulated by RYBP to support a histone modification-dependent communication between polycomb repressive complexes in mice.
