    2. Structural and biological characterization gathered experimental evidence proving that Prosys is a member of the Intrinsically Disordered Proteins family. Considering that protein-protein interactions mediated by disordered regions are involved in molecular recognition and signaling events, it is proposed that Prosys may exert its multifaceted biological activity as a consequence of its intrinsic disorder.

    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.
