These MADR1 ELISA kits are immunodetection tools for measuring the levels of MADR1 in biological samples. MADR1 is an alias of the human SMAD1 gene, which encodes the protein, SMAD family member 1. Notably, MADR1 is known to play a role in the morphogenesis of anatomical structure and bone development, among other functions. The SMAD1 protein is 465 amino acid residues in length and 52.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be ubiquitinated and phosphorylated. Other names for this target antigen include BSP-1, BSP1, and JV4-1.
