Anti-SPAL2 antibodies enable researchers to detect and measure the SPAL2 antigen in biological samples. This target is a reported synonym of the SIPA1L2 gene, which encodes signal induced proliferation associated 1 like 2. This protein is known to function in GTPase activation and GPCR signaling pathways, among other biological roles. The human version of SPAL2 has a canonical amino acid length of 1722 residues and a protein mass of 190.4 kilodaltons, although 2 isoforms have been identified. It is reported to be widely expressed in many tissue types.
