Anti-DULP antibodies enable researchers to detect and measure the DULP antigen in biological samples. This target is a reported synonym of the TMUB1 gene, which encodes transmembrane and ubiquitin like domain containing 1. This protein is known to be involved in sterol-regulated ubiquitination and degradation of HMG-CoA reductase HMGCR. The human version of DULP has a canonical amino acid length of 246 residues and a protein mass of 26.3 kilodaltons. It is reported to be widely expressed in many tissue types.
