Rabbit Anti-Human RPL10 (N-terminal) Polyclonal antibody

Mitochondrial genomes of plants are much larger than those of mammals and often contain conserved open reading frames (ORFs) of unknown function. Here, we show that one of these conserved ORFs is actually the gene for ribosomal protein L10 (rpl10) in plant. No rpl10 gene has heretofore been reported in any mitochondrial genome other than the exceptionally gene-rich genome of the protist Reclinomonas americana. Conserved ORFs corresponding to rpl10 are present in a wide diversity of land plant and green algal mitochondrial genomes. The mitochondrial rpl10 genes are transcribed in all nine land plants examined, with five seed plant genes subject to RNA editing. In addition, mitochondrial-rpl10-like cDNAs were identified in EST libraries from numerous land plants. In three lineages of angiosperms, rpl10 is either lost from the mitochondrial genome or a pseudogene. in two of them (Brassicaceae and monocots), no nuclear copy of mitochondrial rpl10 is identifiably present, and instead a second copy of nuclear-encoded chloroplast rpl10 is present. Transient assays using green fluorescent protein indicate that this duplicate gene is dual targeted to mitochondria and chloroplasts. We infer that mitochondrial rpl10 has been functionally replaced by duplicated chloroplast counterparts in Brassicaceae and monocots.

Intellectual disability is a neurodevelopmental disorder of impaired adaptive skills and low intelligence quotient. The overall prevalence is estimated at 2-3% in the general population with extreme clinical and genetic heterogeneity, and it has been associated with possibly causative mutations in more than 700 identified genes. In a recent review, among over 100 X-linked intellectual disability causative genes, eight were reported as "awaiting replication." Exome sequencing in a large family identified a missense mutation in RPL10 highly suggestive of X-linked intellectual disability. Herein, we report on the clinical description of four affected males. All patients presented apparent intellectual disability (4/4), psychomotor delay (4/4) with syndromic features including amniotic fluid excess (3/4), microcephaly (2/4), urogenital anomalies (3/4), cerebellar syndrome (2/4), and facial dysmorphism. In the literature, two mutations were reported in three families with affected males presenting with autism. This report confirms the implication of RPL10 mutations in neurodevelopmental disorders and extends the associated clinical spectrum from autism to syndromic intellectual disability.
