RPS3 Polyclonal Antibody, AbBy Fluor™ 405 Conjugated

Involved in translation as a component of the 40S small ribosomal subunit (PubMed:8706699) . Has endonuclease activity and plays a role in repair of damaged DNA (PubMed:7775413) . Cleaves phosphodiester bonds of DNAs containing altered bases with broad specificity and cleaves supercoiled DNA more efficiently than relaxed DNA (PubMed:15707971) . Displays high binding affinity for 7,8-dihydro-8-oxoguanine (8-oxoG), a common DNA lesion caused by reactive oxygen species (ROS) (PubMed:14706345) . Has also been shown to bind with similar affinity to intact and damaged DNA (PubMed:18610840) . Stimulates the N-glycosylase activity of the base excision protein OGG1 (PubMed:15518571) . Enhances the uracil excision activity of UNG1 (PubMed:18973764) . Also stimulates the cleavage of the phosphodiester backbone by APEX1 (PubMed:18973764) . When located in the mitochondrion, reduces cellular ROS levels and mitochondrial DNA damage (PubMed:23911537) . Has also been shown to negatively regulate DNA repair in cells exposed to hydrogen peroxide (PubMed:17049931) . Plays a role in regulating transcription as part of the NF-kappa-B p65-p50 complex where it binds to the RELA/p65 subunit, enhances binding of the complex to DNA and promotes transcription of target genes (PubMed:18045535) . Represses its own translation by binding to its cognate mRNA (PubMed:20217897) . Binds to and protects TP53/p53 from MDM2-mediated ubiquitination (PubMed:19656744) . Involved in spindle formation and chromosome movement during mitosis by regulating microtubule polymerization (PubMed:23131551) . Involved in induction of apoptosis through its role in activation of CASP8 (PubMed:14988002) . Induces neuronal apoptosis by interacting with the E2F1 transcription factor and acting synergistically with it to up-regulate pro-apoptotic proteins BCL2L11/BIM and HRK/Dp5 (PubMed:20605787) . Interacts with TRADD following exposure to UV radiation and induces apoptosis by caspase-dependent JNK activation (PubMed:22510408) .
