    Abstract

    The Src associated substrate in mitosis of 68kDa, Sam68, is an RNA-binding protein that belongs to the KH domain family of proteins. KH-type RNA binding proteins are known to mediate high affinity RNA binding and regulate RNA metabolism including pre-mRNA splicing, mRNA export and protein translation. The RNA binding specificity of Sam68 as well as its RNA targets are poorly understood. Herein we cross-linked mRNA associated with Sam68 and identified some of the mRNA associated with the Sam68 RNA binding protein complex. By using this strategy, we have identified 23 mRNAs that are associated with the immunoprecipitated endogenous Sam68 protein complex. Five of the identified mRNAs were validated by co-immunoprecipitation assay followed by reverse transcription PCR confirming that we had indeed identified mRNAs associated with the Sam68 protein complex.

      Related information

      • Related Citations
        Calculated set of PubMed citations closely related to the selected article(s) retrieved using a word weight algorithm. Related articles are displayed in ranked order from most to least relevant, with the “linked from” citation displayed first.
      • Gene
        Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.
      • Gene (GeneRIF)
        Gene records that have the current articles as Reference into Function citations (GeneRIFs). NLM staff reviewing the literature while indexing MEDLINE add GeneRIFs manually.
      • HomoloGene
        HomoloGene clusters of homologous genes and sequences that cite the current articles. These are references on the Gene and sequence records in the HomoloGene entry.
      • Nucleotide (RefSeq)
        NCBI nucleotide Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.
      • Nucleotide (Weighted)
        Nucleotide records associated with the current articles through the Gene database. These are the related sequences on the Gene record that are added manually by NCBI.
      • OMIM (calculated)
        Online Mendelian Inheritance in Man (OMIM) records that include the current articles as references in the light bulb links within or in the citations at the end of the OMIM record. The references available through the light bulb link are collected using the PubMed related articles algorithm to identify records with similar terminology to the OMIM record.
      • Protein (RefSeq)
        NCBI protein Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.
      • Protein (Weighted)
        Protein records associated with the current articles through related Gene database records. These are the related sequences on the Gene record that are added manually by NCBI.
      • Substance (MeSH Keyword)
        PubChem chemical substance (submitted) records that are classified under the same Medical Subject Headings (MeSH) controlled vocabulary as the current articles.
      • Taxonomy via GenBank
        Taxonomy records associated with the current articles through taxonomic information on related molecular database records (Nucleotide, Protein, Gene, SNP, Structure).
      • UniGene
        UniGene clusters of expressed sequences that are associated with the current articles through references on the clustered sequence records and related Gene records.
      • GEO Profiles
        Gene Expression Omnibus (GEO) Profiles of molecular abundance data. The current articles are references on the Gene record associated with the GEO profile.
