Anti-YTHDC1 antibodies are used in the immunodetection of the protein YTH N6-methyladenosine RNA binding protein C1. In humans, the canonical protein has a reported length of 727 amino acid residues and a mass of 84.7 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. YTHDC1 is a reported regulator of alternative splicing that specifically recognizes and binds N6-methyladenosine (m6A)-containing RNAs. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include YTH domain containing 1, putative splicing factor YT521, splicing factor YT521, splicing factor YT521-B, and YTH domain-containing protein 1.
