Rho GTPase activating protein 18 is a protein that in humans is encoded by the ARHGAP18 gene. [1] The gene is also known as MacGAP and bA307O14.2. [1] ARHGAP18 belongs to a family of Rho GTPase-activating proteins that modulate cell signaling. [2]

Model organisms have been used in the study of ARHGAP18 function. A conditional knockout mouse line, called Arhgap18tm1a(KOMP)Wtsi [7] [8] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists. [9] [10] [11]
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. [5] [12] Twenty three tests were carried out on mutant mice and one significant abnormality was observed. [5] Fewer than expected homozygous mutant embryos were identified during gestation. [5]
Trpc4-associated protein is a protein that in humans is encoded by the TRPC4AP gene.
ARF GTPase-activating protein GIT2 is an enzyme that in humans is encoded by the GIT2 gene.
Centromere protein J is a protein that in humans is encoded by the CENPJ gene. It is also known as centrosomal P4.1-associated protein (CPAP). During cell division, this protein plays a structural role in the maintenance of centrosome integrity and normal spindle morphology, and it is involved in microtubule disassembly at the centrosome. This protein can function as a transcriptional coactivator in the Stat5 signaling pathway and also as a coactivator of NF-kappaB-mediated transcription, likely via its interaction with the coactivator p300/CREB-binding protein.
AT-rich interactive domain-containing protein 2 (ARID2) is a protein that in humans is encoded by the ARID2 gene.
Disco-interacting protein 2 homolog A is a protein that in humans is encoded by the DIP2A gene.
Guanine nucleotide exchange factor DBS is a protein that in humans is encoded by the MCF2L gene.
Mitochondrial Rho GTPase 1 (MIRO1) is an enzyme that in humans is encoded by the RHOT1 gene on chromosome 17. As a Miro protein isoform, the protein facilitates mitochondrial transport by attaching the mitochondria to the motor/adaptor complex. Through its key role in mitochondrial transport, RHOT1 is involved in mitochondrial homeostasis and apoptosis, as well as Parkinson’s disease (PD) and cancer.
Arf-GAP with GTPase, ANK repeat and PH domain-containing protein 1 is an enzyme that in humans is encoded by the AGAP1 gene.
RhoU is a small signaling G protein, and is a member of the Rho family of GTPases. Wrch1 was identified in 2001 as encoded by a non-canonical Wnt induced gene. RhoU/Wrch delineates with RhoV/Chp a Rho subclass related to Rac and Cdc42, which emerged in early multicellular organisms during evolution.
Rho-related BTB domain-containing protein 3 is a protein that in humans is encoded by the RHOBTB3 gene.
N-terminal EF-hand calcium-binding protein 2 is a protein that in humans is encoded by the NECAB2 gene.
StAR-related lipid transfer domain protein 13 (STARD13) also known as deleted in liver cancer 2 protein (DLC-2) is a protein that in humans is encoded by the STARD13 gene and a member of the DLC family of proteins.
Rho guanine nucleotide exchange factor 4 is a protein that in humans is encoded by the ARHGEF4 gene.
FERM, RhoGEF and pleckstrin domain-containing protein 2 is a protein that in humans is encoded by the FARP2 gene.
StAR-related lipid transfer domain protein 8 (STARD8) also known as deleted in liver cancer 3 protein (DLC-3) is a protein that in humans is encoded by the STARD8 gene and is a member of the DLC family.
Solute carrier family 41, member 3 is a protein that in humans is encoded by the SLC41A3 gene.
Rho GTPase activating protein 25 is a protein that in humans is encoded by the ARHGAP25 gene. The gene is also known as KAIA0053. ARHGAP25 belongs to a family of Rho GTPase-modulating proteins that are implicated in actin remodeling, cell polarity, and cell migration.
Malignant Brain Tumor domain containing 1 is a protein that in humans is encoded by the MBTD1 gene. The gene is also known as SA49P01.
Transmembrane protein 165 is a protein that in humans is encoded by the TMEM165 gene.
RAB7, member RAS oncogene family-like 1 is a protein that in humans is encoded by the RAB7L1 gene. The gene is also known as RAB7L. RAB7L1 encodes a small GTP-binding protein and is a member of the Ras superfamily.
