Crystal structure of human Ribosomal protein L10 core domain
Structural highlights
DiseaseRL10_HUMAN Defects in RPL10 are a cause of susceptibility to autism X-linked type 5 (AUTSX5) [MIM:300847. A complex multifactorial, pervasive developmental disorder characterized by impairments in reciprocal social interaction and communication, restricted and stereotyped patterns of interests and activities, and the presence of developmental abnormalities by 3 years of age. Most individuals with autism also manifest moderate mental retardation. Note=RPL10 is involved in autism only in rare cases. Two hypomorphic variants affecting the translation process have been found in families with autism spectrum disorders, suggesting that aberrant translation may play a role in disease mechanisms.[1] [2] FunctionEvolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedA phylogenetically conserved ribosomal protein L16p/L10e organizes the architecture of the aminoacyl tRNA binding site on the large ribosomal subunit. Eukaryotic L10 also exhibits a variety of cellular activities, and, in particular, human L10 is known as a putative tumor suppressor, QM. We have determined the 2.5-A crystal structure of the human L10 core domain that corresponds to residues 34-182 of the full-length 214 amino acids. Its two-layered alpha+beta architecture is significantly similar to those of the archaeal and bacterial homologues, substantiating a high degree of structural conservation across the three phylogenetic domains. A cation-binding pocket formed between alpha2 and beta 6 is similar to that of the archaeal L10 protein but appears to be better ordered. Previously reported L10 mutations that cause defects in the yeast ribosome are clustered around this pocket, indicating that its integrity is crucial for its role in L10 function. Characteristic interactions among Arg90-Trp171-Arg139 guide the C-terminal part outside of the central fold, implying that the eukaryote-specific C-terminal extension localizes on the outer side of the ribosome. Crystal structure of human ribosomal protein L10 core domain reveals eukaryote-specific motifs in addition to the conserved fold.,Nishimura M, Kaminishi T, Takemoto C, Kawazoe M, Yoshida T, Tanaka A, Sugano S, Shirouzu M, Ohkubo T, Yokoyama S, Kobayashi Y J Mol Biol. 2008 Mar 21;377(2):421-30.
