    Title: DDX43 mRNA expression and protein levels in relation to clinicopathological profile of breast cancer.
  2. DDX43 prefers single-strand DNA or RNA with length longer than 12nt and much prefers guanosine than the other three nucleotides. Achievement of the full binding affinity of protein to substrate needs the existence of all domains, and they must be connected. The absence of either of them or the disjunction can result in a decreased binding affinity to substrates, approximately reduced 10-fold.

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.
