Anti-SPDYE antibodies enable researchers to detect and measure the SPDYE antigen in biological samples. This target is a reported synonym of the SPDYE1 gene, which encodes speedy/RINGO cell cycle regulator family member E1. The human version of SPDYE has a canonical amino acid length of 336 residues and a protein mass of 40.7 kilodaltons. It is reported to be notably expressed in the testis. SPDYE is a member of the Speedy/Ringo protein family.
