Rho GTPase activating protein 21 is a protein that in humans is encoded by the ARHGAP21 gene. [5]
ARHGAP21 functions preferentially as a GTPase-activating protein (GAP) for CDC42 (MIM 116952) and regulates the ARP2/3 complex (MIM 604221) and F-actin dynamics at the Golgi through control of CDC42 activity (Dubois et al., 2005 [PubMed 15793564]). There is little scientific literature on ARHGAP21, but recent reviews highlighted that it plays an important role in cytoskeletal processes in cancer, substance transport within the cell, and insulin secretion [6]
ADP-ribosylation factor 6 (ARF6) is a member of the ADP ribosylation factor family of GTP-binding proteins. ARF6 has a variety of cellular functions that are frequently involved in trafficking of biological membranes and transmembrane protein cargo. ARF6 has specifically been implicated in endocytosis of plasma membrane proteins and also, to a lesser extent, plasma membrane protein recycling.
FYVE, RhoGEF and PH domain-containing protein 1 (FGD1) also known as faciogenital dysplasia 1 protein (FGDY), zinc finger FYVE domain-containing protein 3 (ZFYVE3), or Rho/Rac guanine nucleotide exchange factor FGD1 is a protein that in humans is encoded by the FGD1 gene that lies on the X chromosome. Orthologs of the FGD1 gene are found in dog, cow, mouse, rat, and zebrafish, and also budding yeast and C. elegans. It is a member of the FYVE, RhoGEF and PH domain containing family.
LIM domain kinase 1 is an enzyme that in humans is encoded by the LIMK1 gene.
Rho GTPase-activating protein 1 is an enzyme that in humans is encoded by the ARHGAP1 gene.
Rac2 is a small signaling G protein, and is a member of the Rac subfamily of the family Rho family of GTPases. It is encoded by the gene RAC2.
Rho guanine nucleotide exchange factor 7 is a protein that in humans is encoded by the ARHGEF7 gene.
Rho GDP-dissociation inhibitor 1 is a protein that in humans is encoded by the ARHGDIA gene.
Formin-binding protein 1 is a protein that in humans is encoded by the FNBP1 gene.
Serine/threonine-protein kinase MRCK alpha is an enzyme that in humans is encoded by the CDC42BPA gene.
Rnd1 is a small signaling G protein, and is a member of the Rnd subgroup of the Rho family of GTPases. It is encoded by the gene RND1.
Rho GTPase-activating protein 5 is an enzyme that in humans is encoded by the ARHGAP5 gene.
Rho GTPase-activating protein 4 is an enzyme that in humans is encoded by the ARHGAP4 gene. It has been shown to regulate cell motility and axonal outgrowth in vitro.
Exocyst complex component 5 is a protein that in humans is encoded by the EXOC5 gene.
Cdc42 effector protein 1 is a protein that in humans is encoded by the CDC42EP1 gene.
The Ras superfamily, derived from "Rat sarcoma virus", is a protein superfamily of small GTPases. Members of the superfamily are divided into families and subfamilies based on their structure, sequence and function. The five main families are Ras, Rho, Ran, Rab and Arf GTPases. The Ras family itself is further divided into 6 subfamilies: Ras, Ral, Rap, Rheb, Rad and Rit. Miro is a recent contributor to the superfamily. Each subfamily shares the common core G domain, which provides essential GTPase and nucleotide exchange activity.
Rho GTPase-activating protein 32 is a protein that in humans is encoded by the RICS gene. RICS has two known isoforms, RICS that are expressed primarily at neurite growth cones, and at the post synaptic membranes, and PX-RICS which is more widely expressed in the endoplasmic reticulum, Golgi apparatus and endosomes. The only known domain of the RICS is the RhoGAP domain, whilst PX-RICS has an additional Phox homology and SH3 domain.
Rho GTPase activating protein 26 (ARHGAP26) also known as GTPase Regulator Associated with Focal Adhesion Kinase (GRAF) is a protein that in humans is encoded by the ARHGAP26 gene.
SLIT-ROBO Rho GTPase-activating protein 3 is an enzyme that in humans is encoded by the SRGAP3 gene.
Rho GTPase-activating protein 8 is a protein that in humans is encoded by the ARHGAP8 gene.
The Rho GTPase activating protein 31 is encoded in humans by the ARHGAP31 gene. It is a Cdc42/Rac1 GTPase regulator.
