Anti-MYT1L antibodies are used in the immunodetection of the protein myelin transcription factor 1 like. In humans, the canonical protein has a reported length of 1186 amino acid residues and a mass of 133 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of a the MYT1 protein family, MYT1L is reported to be a transcription factor that plays a key role in neuronal differentiation by specifically repressing expression of non-neuronal genes during neuron differentiation. Synonyms for this target antigen include NZF1, ZC2H2C2, ZC2HC4B, myelin transcription factor 1-like protein, neural zinc finger transcription factor 1, and MRD39.
