gtpbinding protein fragment, g alpha

G-Protein antagonist peptide acetate is a truncated substance P-related peptide, competes with receptor for G protein binding. G-Protein antagonist peptide acetate inhibits the activation of Gi or Go by M2 muscarinic cholinergic receptor (M2 mAChR) or of Gs by beta-adrenergic receptor in the reconstituted phospholipid vesicles, assayed by receptor-promoted GTP hydrolysis

Interphotoreceptor Retinoid Binding Protein Fragment (IRBP) is a 20-residue peptide, which is a major pathogenic epitope. It exists in the first homologous repeat of interstitial visual pigment Binding Protein peptide (IRBP 161-180) and can induce post-uv

Using specific antisera raised against synthetic peptides, we find that three distinct GTP-binding protein alpha subunits remain bound to the plasma membrane even after activation with nonhydrolyzable GTP analog. Trypsin cleaves each alpha subunit at a si

Rabies Virus Matrix Protein Fragment (RV-MAT), a polypeptide, selectively binds to the acetylcholine receptor (AChR) located on the cell surface [1].

Protease inhibitor

Alpha-1 antitrypsin (A1AT) is known as a serum trypsin inhibitor and is a protease inhibitor belonging to the serpin superfamily. Alpha-1 antitrypsin is a single-chain glycoprotein consisting of 394 amino acids in the mature form and exhibits a number of

Tumor protein p53 binding protein (53BP1) has been identified in a yeast two-hybrid screen as a protein that interacts with the central DNA–binding domain of p532. Similar to breast cancer susceptibility gene 13, 4 (BRCA1; 53BP1 enhances p53-dependent tra

Substance P-related peptide that inhibits binding of G proteins to their receptors. Competitively and reversibly inhibits M2 muscarinic receptor activation of Gi or Go and inhibits Gs activation by β-adrenoceptors.

Amyloid A proteins (H2N-Ala-Gly-Leu-Pro-Glu-Lys-Tyr-OH) are a family of apolipoproteins associated with high-density lipoprotein in plasma. Different isoforms of SAA are expressed constitutively at different levels or in response to inflammatory stimuli.
