http://purl.uniprot.org/citations/2294106http://www.w3.org/2000/01/rdf-schema#comment"Caenorhabditis elegans adapted for survival in high concentrations of Cd(II) express a heavy metal binding protein designated C. elegans metallothionein-like protein or MT-Ce. This protein was purified to homogeneity and characterized. MT-Ce binds 6 mol of Cd(II)/mol protein. The sequence of 39 amino-terminal residues in MT-Ce was determined. A radiolabeled 41-mer oligonucleotide, designed from the partial MT-Ce sequence, was used in conjunction with sucrose gradient centrifugation to obtain size-fractionated poly(A+) RNA enriched in MT-Ce sequences. Subsequently, cloned cDNAs, corresponding to MT-Ce mRNA sequences, were isolated from a lambda ZapII cDNA library prepared from the enriched template mRNA. cDNA and protein sequence analysis revealed that MT-Ce comprises 62 amino acid residues and has a predicted Mr of 6462. Seventeen of the 18 Cys residues in the nematode cadmium-binding protein are included in Cys-X-Cys and X-Cys-Cys-X motifs that are characteristic of mammalian metallothioneins (MTs). However, the resemblance of MT-Ce to mammalian MTs is superficial. The amino acid sequence of MT-Ce is unique, and neither its putative alpha and beta domains nor its Cys residues can be readily aligned with the corresponding regions of other eukaryotic MTs. This suggests that MT-Ce is an example of convergent evolution. The MT-Ce mRNA level in nematodes that were selected and grown with Cd(II) concentrations that are lethal for wild-type worms, was 55-fold higher than the level of MT-Ce mRNA in wild-type C. elegans. Comparison of the sequences of MT-Ce cDNAs revealed the occurrence of two types of MT-Ce mRNA. Each contains an identical coding region, but the cDNAs diverge markedly in their 5'-untranslated regions. This suggests the possibilities of regulation by alternative splicing and/or the presence of multiple MT-Ce genes encoding a single protein, but controlled by different regulatory elements."xsd:string
