The classic "canonical" NF-κB complex is a heterodimer of p50 and RelA, [1] as shown. NF-κB waits for activation in the cytosol, complexed with the inhibitory protein IκBα . Various extracellular signals can enter the cell via membrane receptors and activate the enzyme IκB kinase (IKK).
Transcobalamin I (TC-1), also known as haptocorrin (HC), R-factor, and R-protein is encoded in the human by the TCN1 gene. TC-1 is a glycoprotein produced by the salivary glands of the mouth. It primarily serves to protect cobalamin (Vitamin B12) from acid degradation in the stomach by producing a HC-Vitamin B 12 complex.
The NFKB complex is inhibited by I-kappa-B proteins (NFKBIA, MIM 164008, or NFKBIB), which inactivate NF-kappa-B by trapping it in the cytoplasm. Phosphorylation of serine residues on the I-kappa-B proteins by kinases (IKBKA, MIM 600664 or IKBKB, MIM 603258) marks them for destruction via the ubiquitination pathway, thereby allowing activation ...
Prothrombin complex concentrate (PCC), also known as factor IX complex, sold under the brand name Kcentra among others, is a combination medication made up of blood clotting factors II, IX, and X [9] (3-factor PCC) or, when also containing factor VII as does Kcentra, 4-factor PCC. [10]
By the early 1930s, this same pigment had been isolated from a range of sources, and recognised as a component of the vitamin B complex. Its structure was determined and reported in 1935 and given the name riboflavin , derived from the ribityl side chain and yellow colour of the conjugated ring system.
When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...
Dinner “Beef” and Broccoli Stir Fry. In a large skillet or wok over medium, heat 1 Tbsp olive oil. Add 1 cup cubed tempeh and cook until golden brown on all sides, 5 to 7 minutes.
The trithorax complex activates gene transcription by inducing trimethylation of lysine 4 of histone H3 at specific sites in chromatin recognized by the complex. [1] Ash1 domain is involved in H3K36 methylation. Trithorax complex also interacts with CBP (CREB binding protein) which is an acetyltransferase to acetylate H3K27. [3]
