Anti-HSPC135 antibodies enable researchers to detect and measure the HSPC135 antigen in biological samples. This target is a reported synonym of the GTPBP8 gene, which encodes GTP binding protein 8 (putative). The human version of HSPC135 has a canonical amino acid length of 284 residues and a protein mass of 32.1 kilodaltons, although 3 isoforms have been identified. It is reported to be widely expressed in many tissue types. HSPC135 is a member of the EngB GTPase protein family.
