Anti-RUTBC1 antibodies enable researchers to detect and measure the RUTBC1 antigen in biological samples. This target is a reported synonym of the SGSM2 gene, which encodes small G protein signaling modulator 2. This protein is known to function in GTPase activation, among other biological roles. The human version of RUTBC1 has a canonical amino acid length of 1006 residues and a protein mass of 113.3 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. RUTBC1 is a member of the RUTBC protein family.
