loop

GroES mobile loop is a flexible region of unbound GroES that interacts with GroEL via the residues located at the tip of the loop.

D-loop peptide, synthetic is an antigenic peptide. It cyclizes through a peptide bond between the side chain carboxylic group of Asp10 and the terminal amide of the peptide.

C-MYC PEPTIDE EPITOPE TFA, the product of the c-myc proto-oncogene, is a helix-loop-helix leucine zipper phosphoprotein that regulates gene transcription in cell proliferation, cell differentiation and apoptosis. This peptide is a human c-myc epitope.

TNF-α antagonist is an exocyclic peptide that mimics the critical TNF-α recognition loop on TNF receptor I complex and, thus, prevents ligand interaction with the receptor. By blocking the TNF receptor ligand contact site, this peptide interferes with both activating receptor activator of NF-κB (RANK) and TNF-α's recruitment and activation of osteoclasts. TNF-α antagonist has been used to block bone resorption in the study of systemic bone loss in rheumatoid arthritis and inflammatory bone destruction.

Gap 26 TFA, a gap junction blocker, is a connexin mimetic peptide derived from the amino acid sequence 63-75 in the first extracellular loop of connexin 43, featuring the SHVR amino acid motif [1].

Dynorphin A (1-10) (TFA), an endogenous opioid neuropeptide, interacts with the extracellular loop 2 of the κ-opioid receptor and inhibits NMDA-activated currents with an IC50 of 42.0 μM.

Connexin mimetic peptide 40GAP27, corresponding to the GAP27 domain of the second extracellular loop of the dominant vascular connexin (Cx40), designated as 40Gap27, is a biologically active peptide utilized to study the pathways by which oxidant stress hinders gap junction communication. Administered 40Gap27 attenuates endothelium-dependent subintimal smooth muscle hyperpolarization.

Connexin mimetic peptide 40,37GAP26, a biologically active peptide, matches the GAP26 domain of the extracellular loop of major vascular connexins Cx37 and Cx40, referred to as 37,40Gap26 based on Cx homology. It has been utilized to examine gap junctions' involvement in propagating endothelial hyperpolarizations induced by cyclopiazonic acid (CPA) in the rodent iliac artery wall. Abundant gap junction plaques comprising Cx37 and Cx40 are present in the endothelium, and the peptide exerts inhibitory actions on subintimal hyperpolarization.

Gap19 is a peptide that corresponds to a sequence on the cytoplasmic loop (CL) of Cx43.

CNP, a member of the natriuretic peptide family, was first identified in porcine brain and later found in other mammals as well as non-mammals. Processing of the CNP precursor gives rise to CNP-22 and its N-terminally elongated form, CNP-53. The CNPs shar

Dynorphin A (1-10), an endogenous opioid neuropeptide, interacts with the κ-opioid receptor by binding to its extracellular loop 2 and inhibits NMDA-activated current, demonstrating an IC50 value of 42.0 μM.

Dynorphin A (1-10) acetate is an endogenous opioid neuropeptide, binds to extracellular loop 2 of the κ-opioid receptor. Dynorphin A (1-10) also blocks NMDA-activated current with an IC50 of 42.0 μM.

Corza6 is a potent and selective peptide inhibitor of the human voltage-gated proton channel (hHv1). It binds to the external voltage sensor domain (VSD) loop in hHv1 at a resting membrane potential (RMP) of natural hyperpolarization in mammalian cells with a Kd of approximately 1 nM. Corza6 facilitates sperm capacitation and permits sustained production of reactive oxygen species (ROS) in leukocytes (WBC).
