    Summary
    Enables molecular adaptor activity. Involved in protein stabilization. Predicted to be located in cytoplasm and nuclear body. Predicted to be part of TTT Hsp90 cochaperone complex. Predicted to be active in cytosol. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Orthologous to human TELO2 (telomere maintenance 2).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
