Eukaryotic Release Factor (eRF)
Eukaryotic release factors terminate protein biosynthesis by recognizing stop codons and promoting peptidyl-tRNA hydrolysis on the ribosome[1][2]. Mechanistically, eRF1 recognizes UAA, UAG, and UGA stop codons, whereas eRF3 acts as a GTPase that cooperates with eRF1 to accelerate nascent polypeptide release[2][3]. In mRNA quality control, eRF1 and eRF3 also participate in the SMG1-UPF1-eRF1-eRF3 SURF complex that links translation termination to nonsense-mediated mRNA decay[4]. In disease models, premature termination codon readthrough provides an experimental route for studying nonsense-mutation disorders, and eRF3 degradation enhances G418-induced readthrough while altering NMD-related protein levels[5]. Compared with eRF3b, eRF3a silencing markedly increases premature nonsense codon readthrough in human cells, while eRF3b overexpression compensates for termination defects caused by eRF3a depletion[6]. Therefore, eRF3a and eRF3b are not fully equivalent release-factor isoforms, because eRF3a mainly maintains mammalian termination-complex formation and eRF1 stability[6]. For experimental applications, eRF3a degraders including CC-90009, CC-885, and SJ6986 support studies of premature stop codon readthrough and CFTR nonsense-mutation rescue[5][7].eRF research connects translation termination, stop codon recognition, GTP hydrolysis, and nonsense-mediated decay.
eRF3a and eRF3b isoform differences guide mammalian termination-complex and readthrough experiments.
eRF3a degraders support CFTR nonsense mutation rescue and premature stop codon readthrough studies.

ABS-752 hydrochloride
0 ImagesABS-752 hydrochloride is an orally active prodrug targeting CRBN-modulating molecular glue with selectivity in protein degradation. ABS-752 hydrochloride preferentially degrades GSPT1 and induces cytotoxicity through this degradation, while it also degrades NEK7, SALL4 and CK1α, with weaker degradation potency against CK1α. As a prodrug, ABS-752 hydrochloride requires metabolic activation to ABT-002 to form the active complex; VAP-1 mediates its conversion to an aldehyde intermediate. ABS-752 hydrochloride induces cell death, reduces cell viability, and exhibits antitumor activity, leading to regression and inhibition of tumor growth. ABS-752 hydrochloride shows no cytotoxicity in primary human hepatocytes. ABS-752 hydrochloride can be used in the research of hepatocellular carcinoma.
