The following tetratricopeptide repeat domain 21A ELISA kits are useful research tools for the measurement of tetratricopeptide repeat domain 21A in biological samples. In humans this protein is encoded by the TTC21A gene. This protein has been described to function in spermatid development. The canonical protein structure is reported to have an amino acid length of 1320 residues, a mass of 150.9 kDa, and is a member of the TTC21 protein family. It is reported to be highly expressed in testis. As many as 5 protein isoforms have been reported. The gene encoding this protein has been associated with the disease, Spermatogenic failure. This protein may also be known as TPR domain containing STI2, TPR repeat protein 21A, stress-inducible protein 2, testicular tissue protein Li 212, and tetratricopeptide repeat protein 21A.
