  • KRAS acts as a molecular on/off switch, using protein dynamics. (wikipedia.org)

  • It does not share significant sequence homology with other subtypes of small G-protein GEF motifs such as the Cdc25 domain and the Sec7 domain, which specifically interact with Ras and ARF family small GTPases, respectively, nor with other Rho protein interactive motifs, indicating that the Dbl family proteins are evolutionarily unique.

  • Second, both strongly transforming retroviruses and non-virus induced malignancies, including human cancers, contain comparable oncogenes. (alliedacademies.org)
  • These proteins recently emerged as important therapeutic targets in NUT midline carcinoma and several types of hematopoietic cancers. (ox.ac.uk)
  • All of this research has demonstrated that oncogene expression is essential not just for cancer development but also for disease maintenance, keeping oncogenes in the spotlight as important anti-cancer treatment targets. (alliedacademies.org)
  • It has been hypothesized that inactivation of the RASSF1A tumor suppressor facilitates K-RAS-mediated transformation by uncoupling it from apoptotic pathways such as the Hippo pathway. (cancerindex.org)
  • The central dogma of molecular biology states that the transfer of genetic information within cells transpires sequentially from DNA to RNA to proteins, whose coding sequences comprise a paltry 1.5-2% of the human genome [ 2 , 3 ]. (biomedcentral.com)
  • This kinase is a catalytic subunit of the protein kinase complex that is important for cell cycle G1 phase progression and G1/S transition. (cancerindex.org)
  • CIP2A cooperates with H-Ras to promote epithelial-mesenchymal transition in cervical-cancer progression. (univ-paris5.fr)
  • Despite the fact that proto-oncogenes are expressed in all cells, including immune cells, abnormalities in proto-oncogenes have been thoroughly characterised and analysed mostly in tumour cells. (alliedacademies.org)

  • This protein aids in the healthy division and development of breast cells. (alliedacademies.org)
  • In eukaryotic cells, protein transport through the secretory and endocytic pathways is mediated by vesicular intermediates. (embl.de)
  • Organisms amenable to easy genetic analysis should prove helpful in assessing the function of at least those proto-oncogene products which are highly conserved in different eukaryotic cells. (embl.de)

  • Cells genetically engineered for Akt hyperactivation or p53/Rb inactivation did not compromise JQ1 efficacy, suggesting that these frequently mutated signaling pathways may not confer resistance to JQ1. (ox.ac.uk)
  • With the increased understanding of molecular mechanisms and basic pathways in the pathogenesis of squamous cell cancer of the head and neck , these pathways may be modified, and rational approaches in cancer therapy at the molecular level may be created. (medscape.com)
  • The proteins encoded by members of the Dbl family share a common domain, presented in this entry, of about 200 residues (designated the Dbl homology or DH domain) that has been shown to encode a GEF activity specific for a number of Rho family members. (embl-heidelberg.de)
  • An amino-terminal portion conserved among a subset of Dbl family proteins is sufficient for the binding of Gbetagamma. (embl-heidelberg.de)
  • CDK4 is a member of the Ser/Thr protein kinase family. (thermofisher.com)
