Anti-ZNF598抗体

靶点信息

E3 ubiquitin-protein ligase that plays a key role in the ribosome quality control (RQC), a pathway that takes place when a ribosome has stalled during translation, leading to degradation of nascent peptide chains (PubMed : 28065601, PubMed : 28132843, PubMed : 28685749, PubMed : 32099016, PubMed : 32579943, PubMed : 33581075). ZNF598 is activated when ribosomes are stalled within an mRNA following translation of prematurely polyadenylated mRNAs (PubMed : 28065601, PubMed : 28132843, PubMed : 28685749). Acts as a ribosome collision sensor : specifically recognizes and binds collided di-ribosome, which arises when a trailing ribosome encounters a slower leading ribosome, leading to terminally arrest translation (PubMed : 28065601, PubMed : 28132843, PubMed : 28685749, PubMed : 30293783). Following binding to colliding ribosomes, mediates monoubiquitination of 40S ribosomal proteins RPS10/eS10 and RPS3/uS3, and 'Lys-63'-linked polyubiquitination of RPS20/uS10 (PubMed : 28065601, PubMed : 28132843, PubMed : 28685749). Polyubiquitination of RPS20/uS10 promotes recruitment of the RQT (ribosome quality control trigger) complex, which drives the disassembly of stalled ribosomes, followed by degradation of nascent peptides (PubMed : 32099016, PubMed : 32579943, PubMed : 36302773). E3 ubiquitin-protein ligase activity is dependent on the E2 ubiquitin-conjugating enzyme UBE2D3 (PubMed : 28685749). Also acts as an adapter that recruits the 4EHP-GYF2 complex to mRNAs (PubMed : 22751931, PubMed : 32726578). Independently of its role in RQC, may also act as a negative regulator of interferon-stimulated gene (ISG) expression (PubMed : 29719242).. (Microbial infection) Required for poxvirus protein synthesis by mediating ubiquitination of RPS10/eS10 and RPS20/uS10 (PubMed : 29719242). Poxvirus encoding mRNAs contain unusual 5' poly(A) leaders and ZNF598 is required for their translational efficiency, possibly via its ability to suppress readthrough or sliding on shorter poly(A) tracts (PubMed : 29719242).
