Anti-AF1Q antibodies enable researchers to detect and measure the AF1Q antigen in biological samples. This target is a reported synonym of the MLLT11 gene, which encodes MLLT11 transcription factor 7 cofactor. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of AF1Q has a canonical amino acid length of 90 residues and a protein mass of 10.1 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. AF1Q is a member of the MLLT11 protein family.
