VMA21 ELISA kits are immunoassay tools for the measurement of the protein vacuolar ATPase assembly factor VMA21, which is encoded by the VMA21 gene in humans. Functionally, this protein is known to be required for the assembly of the V0 complex of the vacuolar ATPase (V-ATPase) in the endoplasmic reticulum. The canonical protein structure is reported to have an amino acid length of 101 residues, a mass of 11.4 kDa, and is a member of the VMA21 protein family. It is known to be localized in the cytoplasmic vesicles and ER. As many as 2 protein isoforms have been reported. The VMA21 gene has been associated with the disease, Myopathy. Other alias names for this target include VMA21 vacuolar H+-ATPase homolog, VMA21, vacuolar ATPase assembly factor, myopathy with excessive autophagy protein, and vacuolar ATPase assembly integral membrane protein VMA21.
