Anti-SPAL3 antibodies enable researchers to detect and measure the SPAL3 antigen in biological samples. This target is a reported synonym of the SIPA1L3 gene, which encodes signal induced proliferation associated 1 like 3. This protein is known to function in GTPase activation and cytoskeleton organization, among other biological roles. The human version of SPAL3 has a canonical amino acid length of 1781 residues and a protein mass of 194.6 kilodaltons. It is reported to be localized in the cell membrane of cells. This target antigen may also be known as CTRCT45.
