RACGAP1
Rac GTPase-activating protein 1 is an enzyme that in humans is encoded by the ''RACGAP1'' gene. Function Rho GTPases control a variety of cellular processes. There are 3 subtypes of Rho GTPases in the Ras superfamily of small G proteins: RHO (see MIM 165370), RAC (see RAC1; MIM 602048), and CDC42 (MIM 116952). GTPase-activating proteins (GAPs) bind activated forms of Rho GTPases and stimulate GTP hydrolysis. Through this catalytic function, Rho GAPs negatively regulate Rho-mediated signals. GAPs may also serve as effector molecules and play a role in signaling downstream of Rho and other Ras-like GTPases. upplied by OMIM Over-expression of RACGAP1 is observed in multiple human cancers including breast cancer, gastric cancer and colorectal cancer. Evidence show that RACGAP1 can modulate mitochondrial quality control by stimulating mitopahy and mitochondrial biogenesis in breast cancer. Knocking out RACGAP1 in vitro using CRISPR/Cas9 leads to cytokinesis failure. Interactions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rnd2
Rnd2 is a small (~21 kDa) signaling G protein (to be specific, a GTPase), and is a member of the Rnd subgroup of the Rho family of GTPases. It is encoded by the gene RND2. Function It contributes to regulating the organization of the actin cytoskeleton in response to extracellular growth factors (Nobes et al., 1998). upplied by OMIMref name="entrez2"> This particular family member has been implicated in the regulation of neuronal morphology and endosomal trafficking. Clinical significance The gene localizes to chromosome 17 and is the centromeric neighbor of the breast-ovarian cancer susceptibility gene BRCA1.

SLC26A8
Testis anion transporter 1 is a protein that in humans is encoded by the ''SLC26A8'' gene. Function This gene is one member of a family of sulfate/anion transporter genes. Family members are well conserved in their genomic (number and size of exons) and protein (aa length among species) structures yet have markedly different tissue expression patterns. This gene is expressed primarily in spermatocytes. Two transcript variants encoding different isoforms have been found. Interactions SLC26A8 has been shown to interact with RACGAP1 Rac GTPase-activating protein 1 is an enzyme that in humans is encoded by the ''RACGAP1'' gene.

Enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...

Gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAC1
Ras-related C3 botulinum toxin substrate 1, is a protein that in humans is encoded by the ''RAC1'' gene. This gene can produce a variety of alternatively spliced versions of the Rac1 protein, which appear to carry out different functions. Function Rac1 is a small (~21 kDa) signalling G protein (more specifically a GTPase), and is a member of the Rac subfamily of the family Rho family of GTPases. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of GLUT4 translocation to glucose uptake, cell growth, cytoskeletal reorganization, antimicrobial cytotoxicity, and the activation of protein kinases. Rac1 is a pleiotropic regulator of many cellular processes, including the cell cycle, cell-cell adhesion, motility (through the actin network), and of epithelial differentiation (proposed to be necessary for maintaining epidermal stem cells). Role in glucose transport Rac1 is expressed in significant amounts in insulin sensiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
