Specificity: ARHGEF7 Antibody detects endogenous levels of total ARHGEF7. Immunogen: A synthesized peptide derived from human ARHGEF7, corresponding to a region within the internal amino acids. Uniprot: Q14155 Description: Cool/Pix proteins comprise a family of guanine nucleotide exchange factors (GEFs) localized to focal adhesions. The family consists of two isoforms, cool2/αpix and cool1/βPix, the latter having two splice variants that vary in their carboxy termini (1). Cool1/βPix, like other GEFs, has a DH (Dbl homology) domain, which allows binding of small GTPases and GDP/GTP exchange, and a PH (Pleckstrin homology) domain, which is important in regulating subcellular localization. Cool1/βPix also has an SH3 domain, which binds to the PAK kinase, a downstream effector of cdc42 and Rac (3,4). Phosphorylation of cool1/βPix by PAK2 downstream of MAPK signaling alters the localization of a complex containing PAK2 and cool-1/βPix, regulating formation of growth cones in response to growth factors (4). Growth factor induced activation of Rac1 via cool1/βPix was later shown to occur independently of subcellular localization (5). Endothelin-1 stimulation of mesangial cells stimulates the protein kinase A (PKA) pathway, resulting in translocation of cool-1/βPix and activation of cdc42 (6).

It is an essential (20 30 kDa) GTP-binding proteins (Adams et al., 1990; Johnson regulator of polarized morphogenesis in epithelial cells, through and Pringle, 1990). It is part of the Ras-homologous Rho subfamily coordination of apical membrane morphogenesis, lumen formation and of GTPases, of which there are 20 members in humans, including junction maturation. In parallel, work in yeast and Caenorhabditis elegans the RhoA and Rac GTPases, (Hall, 2012).

ARHGEF7 (B-PIX) Is Required for the Maintenance of Podocyte Architecture and Glomerular Function
BASIC RESEARCH www.jasn.org ARHGEF7 (b-PIX) Is Required for the Maintenance of Podocyte Architecture and Glomerular Function Jun Matsuda, Mirela Maier, Lamine Aoudjit, Cindy Baldwin, and Tomoko Takano Division of Nephrology, McGill University Health Centre, Montreal, Quebec, Canada ABSTRACT Background Previous studies showed that Cdc42, a member of the prototypical Rho family of small GTPases and a regulator of the actin cytoskeleton, is critical for the normal development and health of podocytes. However, upstream regulatory mechanisms for Cdc42 activity in podocytes are largely unknown. Methods We used a proximity-based ligation assay, BioID, to identify guanine nucleotide exchange fac- tors that activate Cdc42 in immortalized human podocytes. We generated podocyte-specificARHGEF7 (commonly known as b-PIX) knockout mice by crossing b-PIX floxed mice with Podocin-Cre mice. Using shRNA, we established cultured mouse podocytes with b-PIX knockdown and their controls. Results We identified b-PIX as a predominant guanine nucleotide exchange factor that interacts with Cdc42 in human podocytes. Podocyte-specific b-PIX knockout mice developed progressive proteinuria and kidney failure with global or segmental glomerulosclerosis in adulthood. Glomerular podocyte density gradually decreased in podocyte-specific b-PIX knockout mice, indicating podocyte loss. Compared with controls, glomeruli from podocyte-specific b-PIX knockout mice and cultured mouse podocytes with b-PIX knockdown exhibited significant reduction in Cdc42 activity. Loss of b-PIX promoted podocyte apoptosis, which was mediated by the reduced activity of the prosurvival transcriptional regulator Yes-associated protein. Conclusions These findings indicate that b-PIX is required for the maintenance of podocyte architecture and glomerular function via Cdc42 and its downstream Yes-associated protein activities.

ABSTRACT Pleckstrin homology (PH) domains are presumed to bind phosphoinositides (PIPs), but specific interaction with and regulation by PIPs for most PH domain-containing proteins are unclear. Here we employed a single-molecule pulldown assay to study interactions of lipid vesicles with full-length proteins in mammalian whole cell lysates.

Glial derived neurotrophic factor (GDNF) interacts with cancer cell RET receptors to enable PNI, but downstream events remain undefined. We demonstrate that GDNF leads to early activation of the GTPase Cdc42 in pancreatic cancer cells, but only delayed activation of RhoA and does not affect Rac1. Depletion of Cdc42 impairs pancreatic cancer cell chemotaxis towards GDNF and nerves.

Differential Expression of PAK3 in Cancers of the Breast
Differential expression of p21 (RAC1) activated kinase 3 in cancers of the breast. Shahan Mamoor, MS1 [email protected] East Islip, NY 11739 Breast cancer affects women at relatively high frequency1. We mined published microarray datasets2,3 to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding p21 (RAC1) activated kinase 3, PAK3, when comparing primary tumors of the breast to the tissue of origin, the normal breast. PAK3 was also differentially expressed in the tumor cells of patients with triple negative breast cancer. PAK3 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of PAK3 in primary tumors of the breast was correlated with post-progression survival in patients with luminal B subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. PAK3 may be of relevance to initiation, maintenance or progression of cancers of the female breast. Keywords: breast cancer, PAK3, p21 (RAC1) activated kinase 3, systems biology of breast cancer, targeted therapeutics in breast cancer. 1 Invasive breast cancer is diagnosed in over a quarter of a million women in the United States each year1 and in 2018, breast cancer was the leading cause of cancer death in women worldwide4. While patients with localized breast cancer are provided a 99% 5-year survival rate, patients with regional breast cancer, cancer that has spread to lymph nodes or nearby structures, are provided an 86% 5-year survival rate5,6.

We report on the cytogenetic and molecular investigations of constitutional de-novo ring chromosome 13s in three unrelated patients for better understanding and delineation of the phenotypic variability characterizing this genomic rearrangement. The patient’s karyotypes were as follows: 46,XY,r(13)(p11q34) dn for patients 1 and 2 and 46,XY,r(13)(p11q14) dn for patient 3, as a result of the deletion in the telomeric regions of chromosome 13. The patients were, therefore, monosomic for the segment 13q34 → 13qter; in addition, for patient 3, the deletion was larger, encompassing the segment 13q14 → 13qter. Fluorescence in situ hybridi- zation confirmed these rearrangement and array CGH technique showed the loss of at least 2.9 Mb on the short arm and 4.7 Mb on the long arm of the chromosome 13 in patient 2. Ring chromosome 13 (r(13)) is associated with several phenotypic features like intellectual disability, marked short stature, brain and heart defects, microcephaly and genital malformations in males, including undescended testes and hypospadias.

New intriguing roles have emerged for Rho family GTPases and their Rho guanine nucleotide exchange factor (GEF) activators in the regulation of glucose homeostasis. This review summates the current knowledge, focusing in particular on the roles of Rho GEFs in the processes of glucose-stimulated insulin secretion by pancreatic β cells and insulin-stimulated glucose uptake into skeletal muscle and adipose tissues. We discuss the ten Rho GEFs that are known so far to regulate glucose homeostasis, nine of which are in mammals, and one is in yeast. Among the mammalian Rho GEFs, P-Rex1, Vav2, Vav3, Tiam1, Kalirin and Plekhg4 were shown to mediate the insulin-stimulated translocation of the glucose transporter GLUT4 to the plasma membrane and/or insulin-stimulated glucose uptake in skeletal muscle or adipose tissue. The Rho GEFs P-Rex1, Vav2, Tiam1 and β-PIX were found to control the glucose-stimulated release of insulin by pancreatic β cells.
