Anti-SPARC-like 1 (hevin) antibodies are protein reagents that detect specific antigens. The SPARC-like 1 (hevin) antigen is another term for the human protein SPARC like 1, encoded by the SPARCL1 gene. The protein is known to function in signal transduction pathways, among other biological roles. Canonically, it has an amino acid length of 664 residues and a mass of 75.2 kilodaltons. Its subcellular localization is in the extracellular matrix and is secreted. The SPARC-like 1 (hevin) protein is a member of the SPARC protein family. Other alias names for SPARC-like 1 (hevin) include MAST 9, MAST9, and PIG33.
