TBC1D21 ELISA kits are immunoassay tools for the measurement of the protein TBC1 domain family member 21, which is encoded by the TBC1D21 gene in humans. Functionally, this protein is known to act as a GTPase-activating protein for Rab family protein(s). The canonical protein structure is reported to have an amino acid sequence of 336 residues and a mass of 39.2 kDa. It is known to be localized in the cytoplasmic vesicles and cytoplasm and is reported to be expressed in round and elongated spermatids. As many as 2 protein isoforms have been reported. The TBC1D21 gene has been associated with the disease, . Other alias names for this target include male germ cell-specific expressed, containing a RabGAP domain, and male germ cell Rab GTPase-activating protein.
