Anti-Hs.78846 antibodies enable researchers to detect and measure the Hs.78846 antigen in biological samples. This target is a reported synonym of the HSPB2 gene, which encodes heat shock protein family B (small) member 2. This protein is believed to regulate the kinase DMPK. The human version of Hs.78846 has a canonical amino acid length of 182 residues and a protein mass of 20.2 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the skeletal muscle, placenta, kidney, and heart muscle. Other names for this target antigen include HSP27, HSP27, and Hs.78846.
