Czh proteins: a new family of rho-gefs
WebDedicator of cytokinesis (DOCK) proteins constitute a family of evolutionarily conserved guanine nucleotide exchange factors (GEFs) for the Rho family of GTPases. Although DOCK family proteins do not contain the Dbl homology domain typically found in other GEFs, they mediate the GTP-GDP exchange reaction through the DOCK homology … WebDec 1, 2024 · DOCK and Dbl families are structurally and mechanistically different Rho GEFs. The DOCK family recognizes Rac or Cdc42 via the difference in the 56th amino acid as well as the conformational difference in switch 1 of GTPases, by using lobes C and B of the DHR-2 domain, respectively. ...

WebHere we describe a procedure derived from the yeast two-hybrid system, in which activation of a mammalian Rho GTPase by its cognate RhoGEF is converted into variation in the yeast growth. The experimental design is thus suitable for identiying RhoGEF inhibitors and has been optimized for medium-throughput screening. WebJul 1, 2008 · The Dock or CZH proteins are a family of activators for Rho GTPase proteins. The Zizimin subfamily is composed of three members: Dock9, Dock10, and Dock11. We have identified DOCK10 as an interleukin-4 (IL4)-inducible gene in chronic lymphocytic leukemias (CLLs).

WebThe small GTPases of the Rho family have been estab-lished as crucial signaling effectors regulating cellular morphology and, consequently, locomotion.1 Activation of RhoA and Rac1, 2 members of the family, has been shown to induce the formation of membrane protrusions and retractions as well as the regulation of actin poly-merisation into ... WebThe activation of Rho GTPases is mediated by guanine-nucleotide exchange factors (GEFs), which catalyze the exchange of GDP for GTP. Rho-GEFs are a very diverse family, with >70 members in humans. Bioinformatics analysis of the human Rho-GEFs shows that ∼40% contain a putative PDZ-binding motif at the C-terminus. PDZ domains …
