A number of ELISA Kits are available that target testis expressed gene 101, an alias of the protein, testis expressed 101. The human protein is encoded by the gene TEX101. The protein's cellular localization is indicated to be membrane-associated and secreted. Additional synonyms or past names for this protein may include: CT131, GTPR867, NYD-SP8, PRO1884, SGRG, SPATA44, TES101RP. Homology is conserved in other species, such as Mouse, Rat.
