A novel superfamily of guanine nucleotide exchange factors for Rho GTPases includes DOCK180 and zizimin1. The zizimin subfamily includes three genes of which only zizimin1 has been cloned. We report here the cloning of zizimin2, identified in a screen for genes enriched in germinal center B cells. Zizimin2 and zizimin1 have similar primary structures and both proteins bound and activated Cdc42 but not the Cdc42‐related proteins TC10 or TCL. Their tissue distributions are distinct, however, with… 
CZH proteins: a new family of Rho-GEFs
TLDR
The Rho family of small GTPases are important regulators of multiple cellular activities and, most notably, reorganization of the actin cytoskeleton, and members of a newly discovered family can also act as Rho-GEFs.
Zizimin and Dock guanine nucleotide exchange factors in cell function and disease
TLDR
The domain structure of Zizimin proteins is discussed from an evolutionary viewpoint and what is currently known about the mammalian ZizIMin proteins to that of related Dock proteins are compared.
Function of the N-terminus of zizimin1: autoinhibition and membrane targeting.
TLDR
It is demonstrated that the N-terminal half of zizimin1 binds to the GEF domain through three distinct areas, including the CZH1, to inhibit the interaction with Cdc42.
Age-related guanine nucleotide exchange factor, mouse Zizimin2, induces filopodia in bone marrow-derived dendritic cells
TLDR
It is suggested that Zizimin2 is an immune-related and age-regulated guanine nucleotide exchange factor, which facilitates filopodial formation through activation of Cdc42, which results in activation of cell migration.
RHO to the DOCK for GDP disembarking: Structural insights into the DOCK GTPase nucleotide exchange factors
TLDR
An overview of the biological and structural characteristics for the various DOCK proteins is provided and how they differ from other RHO GEFs and between DOCK subfamilies is described.
GEF what? Dock180 and related proteins help Rac to polarize cells in new ways.
TLDR
Recent exciting data suggest key roles for the DHR-2 domain-containing GEFs in a wide variety of fundamentally important biological functions, including cell migration, phagocytosis of apoptotic cells, myoblast fusion and neuronal polarization.
Dock180-ELMO cooperation in Rac activation.
TLDR
Dock180 and ELMO function together as a bipartite GEF to optimally activate Rac on upstream stimulation to mediate the engulfment of apoptotic cells and cell migration.
Rat monoclonal antibodies against new guanine nucleotide exchange factor, mouse Zizimin2.
TLDR
Rat monoclonal antibodies against mouse Zizimin2 protein are established and determined their isotypes and further examined capability or availability in immunoblotting, immunoprecipitation, or immunofluorescence microscopy.
Cellular signaling of Dock family proteins in neural function.
TLDR
This review will summarize the newly accumulated findings concerning the Dock180-related proteins' molecular and cellular functions, emphasizing the roles of these proteins in neuronal cells and glial cells as well as their interactions in the central and peripheral nervous systems.
Dock10, a novel CZH protein selectively induced by interleukin-4 in human B lymphocytes.
TLDR
The rapid and distinctive induction of Dock10 expression by IL4 in CLL and normal PB-B cells suggests a role for Dock10 in IL4-induced B-cell activation, and could represent a point of convergence for IL4 signalling and small Rho GTPase function in B cells.

Zizimin1, a novel Cdc42 activator, reveals a new GEF domain for Rho proteins
TLDR
Sequence comparison combined with mutational analysis suggest that CZH2 is a new GEF domain for the Rho family of proteins, a new superfamily that includes the so-called 'CDM' proteins that bind to and activate Rac.
Lck regulates Vav activation of members of the Rho family of GTPases
TLDR
This work presents data indicating that the Lck kinase activates the guanine nucleotide exchange factor and transforming activity of Vav, and reports that Vav has been reported to catalyze GTP-GDP exchange for Ras proteins.
Identification of an evolutionarily conserved superfamily of DOCK180-related proteins with guanine nucleotide exchange activity
TLDR
A novel protein domain is identified named DHR-2 (Dock Homology Region-2) that specifically binds to nucleotide-free Rac and activates Rac in vitro and in vivo and is suggested to be an evolutionarily conserved DOCK180-related superfamily of exchange factors.
Identification of a Novel Guanine Nucleotide Exchange Factor for the Rho GTPase*
TLDR
Results indicate that p115-RhoGEF may be a general regulator of Rho and its associated cellular phenotypes, as determined by its ability to induce the transformation of NIH 3T3 cells.
The Dbl family of oncogenes.
TLDR
There is still a good deal to learn regarding the biochemical mechanisms that underlie the Dbl family of proteins, and these positive regulators of G proteins to specific cellular locations to carry out the signaling task.
GTPases and T cell activation
TLDR
Many members of the Ras family of GTPases, notably Ras and Rap1A, and the Rho family GTPase, are important components of signal transduction pathways used by antigen receptors, costimulatory, cytokine and chemokine receptors to regulate the immune response.
Rho-family GTPases: it's not only Rac and Rho (and I like it)
TLDR
The Rho-family proteins make up a major branch of the Ras superfamily of small GTPases, and newer members of the family possess additional sequence elements beyond the GTPase domain, which suggests they exhibit yet other mechanisms of regulation.
Isolation and characterisation of DOCK8, a member of the DOCK180‐related regulators of cell morphology
TLDR
In a yeast two‐hybrid system screen for Cdc42‐interacting proteins, a protein with similarity to the CrkII‐binding protein DOCK180 was identified and an involvement of DOCK8 in processes that affect the organisation of filamentous actin is suggested.
Functional and physical interactions of Syk family kinases with the Vav proto-oncogene product.
TLDR
The results indicate that the interaction between Syk family kinases and Vav plays an important role in coupling immune recognition receptors to signaling pathways involved in lymphokine production.
Haematopoietic cell-specific CDM family protein DOCK2 is essential for lymphocyte migration
TLDR
It is shown that DOCK2, a haematopoietic cell-specific CDM family protein, is indispensable for lymphocyte chemotaxis and functions as a central regulator that mediates cytoskeletal reorganization through Rac activation.
