Ribosomal protein involved in translational regulation (PubMed:18694459). Contribute to general translation under UV-B stress (PubMed:20516338, PubMed:23886624). Involved in the NIK1-mediated defense response to geminivirus infection (PubMed:18789471, PubMed:19112492). Acts coordinately with LIMYB as a transcriptional repressor (PubMed:25707794). Component of the small ribosomal subunit (PubMed:20516338). Mature ribosomes consist of a small (40S) and a large (60S) subunit. The 40S subunit contains about 33 different proteins and 1 molecule of RNA (18S). The 60S subunit contains about 49 different proteins and 3 molecules of RNA (25S, 5.8S and 5S) (By similarity). Interacts with NIK1 (PubMed:18789471, PubMed:19112492). Interacts with LIMYB (PubMed:25707794). Phosphorylation by NIK1 relocates the cytosolic protein to the nucleus. Ubiquitous, with the highest expression in flowers (PubMed:18694459). Expressed in seedlings, leaves, roots, stems and flowers (PubMed:25707794). Expressed in young leaves, mostly in dividing cells and in the hydathodes, in the root tips and lateral root primordia, in pistils, anthers, and pollen grains, and in developing seeds (PubMed:23886624). Expressed in tissues with active division, with the highest levels in 3-week-old leaves and lowest levels in senescent leaves. Not regulated by UV-B. Phosphorylated by NIK1 and NIK2 in vitro. No visible phenotype, when heterozygous (PubMed:20516338). Lethality in the female gametophyte, when homozygous (PubMed:18694459, PubMed:20516338). Enhanced susceptibility to geminivirus infection (PubMed:18789471, PubMed:19112492). Under UV-B conditions, RPL10 proteins interact with several nuclear proteins, including RBG7 (glycine-rich RNA binding protein), which has an important role in mediating innate immune response to pathogens, and BTR1 that specifically binds to tomato mosaic virus (ToMV) genomic RNA and inhibits the local spread of virus. Belongs to the universal ribosomal protein uL16 family. Truncated N-terminus.
