Description: This gene encodes coagulation factor VIII, which participates in the intrinsic pathway of blood coagulation; factor VIII is a cofactor for factor IXa which, in the presence of Ca+2 and phospholipids, converts factor X to the activated form Xa. This gene produces two alternatively spliced transcripts. Transcript variant 1 encodes a large glycoprotein, isoform a, which circulates in plasma and associates with von Willebrand factor in a noncovalent complex. This protein undergoes multiple cleavage events. Transcript variant 2 encodes a putative small protein, isoform b, which consists primarily of the phospholipid binding domain of factor VIIIc. This binding domain is essential for coagulant activity. Defects in this gene results in hemophilia A, a common recessive X-linked coagulation disorder. [provided by RefSeq, Jul 2008].

Description: Epidermal growth factor (EGF) is an acid- and heat-stable 53 amino acid protein originally found in rodents and humans. It has been shown to be a potent mitogen for a variety of cell types both in vivo and in vitro. EGF binds to the EGF receptor on the surface of cells and mediates intrinsic phosphorylation of the receptor on tyrosine residues. It has been detected in nearly all body fluids, such as urine (urogastrone), saliva, milk and platelet-rich plasma. EGF, TGF?and vaccinia virus growth factor exhibit 30-40% amino acid homology. Several additional members of the EGF/TGF family have been described; these include Cripto, Amphiregulin and the heparin-binding EGF-like growth factor. Amphiregulin and the heparin-binding EGF-like growth factor both bind to the EGF receptor.

Description: The Raf kinases are important intermediates in signal transduction. Raf protein family members, including A Raf and B Raf, have intrinsic serine/threonine kinase activity. Interaction between Ras proteins and Raf proteins results in Raf-mediated phosphorylation and activation of MEK (also known as MAP kinase kinase). Defects in BRAF are involved in a wide range of cancers. B-Raf is a serine/threonine protein kinase that acts as a signal transducer from membrane-associated receptors to nuclear transcription factors. 1 BRAF is important for the regulation of cell proliferation and determination of cell fate during embryogenesis. BRAF acts downstream of Ras and upstream of MEK in the Ras-Raf-MEK-ERK signal transduction pathway, which is a conserved RAS-activated protein kinase cascade that regulates cell growth, proliferation, and differentiation in response to growth factors, cytokines, and hormones.

Description: The expression of DUSP1 gene is induced in human skin fibroblasts by oxidative/heat stress and growth factors. It specifies a protein with structural features similar to members of the non-receptor-type protein-tyrosine phosphatase family, and which has significant amino-acid sequence similarity to a Tyr/Ser-protein phosphatase encoded by the late gene H1 of vaccinia virus. The bacterially expressed and purified DUSP1 protein has intrinsic phosphatase activity, and specifically inactivates mitogen-activated protein (MAP) kinase in vitro by the concomitant dephosphorylation of both its phosphothreonine and phosphotyrosine residues.

Description: Preparation Method: MP Intrinsic Factor is produced from the pylorus mucous membrane of the pig, of which only a small part is used. Only the part which, according to histological examinations has proved to have a high content of Intrinsic Factor, is used.
Applications: Intrinsic Factor is used in the treatment not only of classical pernicious anaemia, but also in the treatment of other macrocytic anaemias, where it replaces the Intrinsic Factor which may be lacking in the patient's own gastric juice. In this way Intrinsic Factor is recommended against anaemias that appear 6 to 12 months after serious gastric operations, and against anaemias that are secondary effects of the treatment with certain medicines, e.g. against epilepsy. However, the dietetic use in multi-vitamin preparations is of the greatest importance. In older people there has been observed a degeneration of the gastric mucous membrane, whose secretion of Intrinsic Factor is insufficient to ensure the resorption of the necessary quantity of B-12 from their diet. In order to delay this development it is useful to prescribe a small quantity of Intrinsic Factor with B-12 and other vitamins to these patients.
Product Description: Intrinsic factor is a glucoprotein extracted from the pylorus part of the gastric mucous membrane. Its presence is considered necessary for the absorption of Vitamin B-12.
Unit Definition: The activity is normally indicated in Coli units, the number of which are proportional to the binding power of the substance to Vitamin B-12.

Application Areas: Absorption of vitamin B12
Product Type: Proteins, Enzymes & Peptides
Presentation: Tan Powder
Foreign activity: Salmonella=Negative, E. coli=Negative
NOTES: Standard Plate Count <1000/g
Solubility: Slightly soluble in toluene; practically insoluble in water.
Storage & Handling: -20°C

Catalog Number: (BOSSBS-3586R-CY7)

Supplier: Bioss

Description: In complex with TSC1, inhibits the nutrient-mediated or growth factor-stimulated phosphorylation of S6K1 and EIF4EBP1 by negatively regulating mTORC1 signaling. Acts as a GTPase-activating protein (GAP) for the small GTPase RHEB, a direct activator of the protein kinase activity of mTORC1. Implicated as a tumor suppressor. Involved in microtubule-mediated protein transport, but this seems to be due to unregulated mTOR signaling. Stimulates weakly the intrinsic GTPase activity of the Ras-related proteins RAP1A and RAB5 in vitro. Mutations in TSC2 lead to constitutive activation of RAP1A in tumors.
