gtp-binding protein fragment, g alpha

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

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(668-687) TFA, a peptide fragment corresponding to amino acids 668-687 of the human interphotoreceptor retinoid-binding protein (IRBP), has been implicated in the induction of uveitis [1].

Acetyl-Heme-Binding Protein 1 (1-21) (human) is a short peptide comprising the initial 21 amino acids of the hemopexin Acetyl-Heme-Binding Protein 1, which is involved in heme binding, heme metabolism, and the release of hemoglobin [1].

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

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

Protease inhibitor

Vitamin D-binding protein is a multifunctional, highly expressed, polymorphic serum protein. These range from the transport of vitamin D metabolites to possible roles in the immune system and host defense. The molecular weight range, the time course of ap

Human vitamin D-binding protein (hDBP) is an abundant, multifunctional, and highly polymorphic serum glycoprotein synthesized by the liver1.

FSH receptor-binding inhibitor fragment (bi-10) is a potent antagonist that inhibits the binding of follicle-stimulating hormone (FSH) to its receptor (FSHR), modifying FSH activity at the receptor level. It suppresses ovulation and induces follicular atresia in mice. Furthermore, this compound holds potential for curbing ovarian cancer carcinogenesis by reducing the overexpression of FSHR and estrogen receptor beta (ERβ) in the ovaries [1].

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

Hepatitis B Virus Receptor Binding Fragment (hepatitis B peptide 4980), a synthetic peptide analog, specifically binds to Hep G2 cells and is a potential immunogen anticipated to induce protective antibodies through the attachment blockade pathway of virus neutralization [1] [2].

Interphotoreceptor retinoid-binding protein(668-687)is an amino acid residue of human retinoid-binding protein(IRBP) 668-687, which can induce uveitis.

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.
