repeat 2 domain

Tau Peptide (275-305), also known as the R2 domain fragment, represents the second repeat unit of the microtubule-binding domain of the Alzheimer's tau peptide. Tau Peptide (275-305) is considered crucial in determining the biochemical characteristics of the complete tau protein.

NSC117079 is a novel PHLPP1/2 (Pleckstrin homology domain and leucine rich repeat protein phosphatase) inhibitor that activates neuronal AKT and ameliorates staurosporine-induced cell death in neurons.

TRF2-IN-1 (compound F2) is a potent inhibitor of telomere repeat-binding factor 2 (TRF2). It exhibits antiproliferative activity and induces apoptosis. TRF2-IN-1 binds directly to the TRF2TRFH domain, selectively inhibiting TRF2 protein expression and telomere localization. Additionally, TRF2-IN-1 possesses anticancer properties and shows potential for osteosarcoma research.

SARS-CoV-2-IN-34 (S-20-1) is a broad-spectrum pan-coronavirus (CoV) fusion inhibitor that penetrates the blood-brain barrier and exhibits extensive inhibitory activity against both pseudotyped and authentic SARS-CoV-2, as well as pseudotyped variants of concern (VOCs). It shows high affinity for the receptor-binding domain (RBD) in the S1 and the heptad repeat 1 (HR1) domain in the S2 of the SARS-CoV-2 spike (S) protein, making it a valuable tool for infection research [1].

Abicipar pegol (AGN-150998, MP0112), an anti-VEGF DARPin molecule, is a novel class of small ankyrin repeat domain-containing proteins designed for high specificity and affinity targeting. This compound effectively inhibits angiogenesis and vascular permeability, and has been applied in ocular inflammation-related disease studies through intravitreal injections, significantly reducing mean retinal thickness and leakage area [1] [2].
