These if1 ELISA kits are immunodetection tools for measuring the levels of if1 in biological samples. if1 is an alias of the human ATP5IF1 gene, which encodes the protein, ATP synthase inhibitory factor subunit 1. Notably, if1 is known to play a role in angiogenesis and erythrocyte differentiation, among other functions. The ATP5IF1 protein is 106 amino acid residues in length and 12.2 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the mitochondria of the cell. Other names for this target antigen include ATPase inhibitor, mitochondrial, ATP synthase inhibitor protein, and ATPase inhibitor protein.
