We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

RPS3 also known as Ribosomal Protein S3 is an important component of the 40S ribosomal subunit. It has a molecular mass of approximately 26 kDa. Functionally RPS3 plays a role in the translation process as part of the ribosome machinery assisting in the assembly of proteins by decoding messenger RNA. Expression of RPS3 is ubiquitous across various tissues suggesting a fundamental role for the protein in cellular functions.
Biological function summary

Protein synthesis relies heavily on components like RPS3 within the ribosomal complex where it interacts with other ribosomal proteins and rRNA to ensure accurate translation. RPS3 also exhibits DNA repair activities independently of its ribosomal function. It binds to DNA damaged sites adding a layer of protection to help maintain genomic stability by facilitating repair processes.

Pathways

RPS3 participates actively in the mRNA translation and DNA repair pathways. Inside the ribosome biogenesis pathway RPS3 interacts closely with other ribosomal proteins like RPS19 and RPS20 to form functional ribosomal units. In the context of DNA repair it aligns with interaction networks that overlap with the NHEJ (Non-Homologous End Joining) pathway thereby influencing genomic maintenance alongside proteins such as XRCC5.

The dysfunction of RPS3 associates with neurodegenerative diseases and certain types of cancer. Aberrant levels or mutations can disrupt protein synthesis and DNA repair mechanisms potentially leading to tumorigenesis. In the context of cancer RPS3 shows interactions with oncogenes such as MYC linking it to pathway disturbances that can facilitate tumor progression. Similarly its misregulation is noticed in neurodegenerative contexts where protein synthesis and repair imbalances contribute to disease pathology.

Target data

Component of the small ribosomal subunit (PubMed : 23636399, PubMed : 8706699). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed : 23636399, 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).
