Anti-RNA binding motif protein Y-linked family 1 member D antibodies are used for the immunodetection of the protein encoded by the RBMY1D gene. In humans, the canonical protein has a reported length of 496 amino acid residues and a mass of 55.8 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to have testis-specific expression. It is reported to be a rna-binding protein, which may be involved in spermatogenesis. Other names for this target antigen include RNA-binding motif protein 1, RNA-binding motif protein 2, RNA-binding motif protein, Y chromosome, family 1 member A1, and RNA-binding motif protein, Y chromosome, family 1 member D.
