  • The KRAS gene encodes a small G protein on the EGFR pathway.
  • Dock11 activates the small G protein Cdc42.
  • The encoded protein directly interacts with a GTPase activating protein that functions downstream of the small G protein Ral.
  • This kinase is activated by Rho family of small G proteins and may mediate the Rho-dependent signaling pathway.
  • However, no stable interaction between Dock8 and these small G proteins was observed in a GST-pulldown assay.
  • Ran is a small G protein that is essential for the translocation of RNA and proteins through the nuclear pore complex.
  • It also associates with a downstream effector of Rho small G proteins, which is associated with the formation of stress fibers and cytokinesis.
  • Dock8 was identified during a yeast two hybrid ( YTH ) screen for proteins that interact with the Rho family small G protein Cdc42.
  • Hence, activation and deactivation of Ras and other small G proteins are controlled by cycling between the active GTP-bound and inactive GDP-bound forms.
  • Activators of each PLC vary, but typically include heterotrimeric G protein subunits, protein tyrosine kinases, small G proteins, Ca 2 +, and phospholipids.
  • The close relationship of DMPK to the Rho-kinases has led to speculation whether DMPK activity may be regulated in vivo by small G proteins, particularly of the Rho family.
  • There are 3 subtypes of Rho GTPases in the Ras superfamily of small G proteins : RHO ( see MIM 165370 ), RAC ( see RAC1; MIM 602048 ), and CDC42 ( MIM 116952 ).
  • The small G protein GDP dissociation stimulator ( HCAP ) and KIF3A / B, a kinesin superfamily protein in the nucleus, and that it plays a role in the interaction of chromosomes with an ATPase motor protein.
  • For example, many GAPs of the small G proteins have a conserved finger-like domain, usually an arginine finger, which changes the conformation of the GTP-bound G protein to orient the GTP for better nucleophilic attack by water.
  • GRASP1 is a neuron-specific guanine nucleotide exchange factor for the Ras family of small G proteins ( RasGEF ) and is associated with the GRIP / AMPA receptor complex in brain ( Ye et al ., 2000 ) . [ supplied by OMIM]
  • They interact with the small GTPase SR-beta, forming a complex that matches a class of small G protein-effector complexes, including Rap-Raf, Ras-PI3K ( gamma ), Ras-RalGDS, and Arl2-PDE ( delta ).
  • It interacts primarily with neutrophil cytosolic factor 2 ( NCF2 / p67-phox ) to form a complex with neutrophil cytosolic factor 1 ( NCF1 / p47-phox ), which further interacts with the small G protein RAC1 and translocates to the membrane upon cell stimulation.
  • "' Dock11 "'( Dedicator of cytokinesis ), also known as "'Zizimin2 "', is a large ( ~ 240 kDa ) protein involved in intracellular DOCK family of guanine nucleotide exchange factors ( GEFs ) which function as activators of small G proteins.
  • "' Dock6 "'( D edicator o f c yto k inesis 6 ), also known as "'Zir1 "'is a large ( ~ 200 kDa ) protein involved in intracellular DOCK family of guanine nucleotide exchange factors which function as activators of small G proteins.
