Anti-yippee like 3 antibodies are used in the immunodetection of the protein encoded by the YPEL3 gene. In humans, the canonical protein has a reported length of 119 amino acid residues and a mass of 13.6 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is widely expressed across many tissue types. A member of the Yippee protein family, it is known to be involved in proliferation and apoptosis in myeloid precursor cells. Post-translational modifications have been described, including ubiquitination. Other names for this target antigen include protein yippee-like 3.
