Anti-FAM107A antibodies are used in the immunodetection of the protein family with sequence similarity 107 member A. In humans, the canonical protein has a reported length of 144 amino acid residues and a mass of 17.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 4 different isoforms for this protein. It is widely expressed across many tissue types. A member of the FAM107 protein family, it is known to be involved with the cell cycle. Synonyms for this target antigen include TU3A, actin-associated protein FAM107A, down-regulated in renal cell carcinoma 1, protein FAM107A, and DRR1.
