Anti-SSH6 antibodies enable researchers to detect and measure the SSH6 antigen in biological samples. This target is a reported synonym of the GPBP1 gene, which encodes GC-rich promoter binding protein 1. This protein is known to function in the regulation of transcription, among other biological roles. The human version of SSH6 has a canonical amino acid length of 473 residues and a protein mass of 53.3 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. SSH6 is a member of the Vasculin protein family.
