Anti-B'-T antibodies enable researchers to detect and measure the B'-T antigen in biological samples. This target is a reported synonym of the ARHGAP11B gene, which encodes Rho GTPase activating protein 11B. This protein is known to function in nervous system development and GPCR signaling pathways, among other biological roles. The human version of B'-T has a canonical amino acid length of 267 residues and a protein mass of 30.3 kilodaltons. It is reported to be localized in the mitochondria of cells.
