Anti-MSRG11 antibodies enable researchers to detect and measure the MSRG11 antigen in biological samples. This target is a reported synonym of the SPATA17 gene, which encodes spermatogenesis associated 17. This protein is known to function in the cell cycle, among other biological roles. The human version of MSRG11 has a canonical amino acid length of 361 residues and a protein mass of 43.5 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the testis, nasopharynx, fallopian tube, and bronchus.
