Anti-PUM antibodies enable researchers to detect and measure the PUM antigen in biological samples. This target is a reported synonym of the MYOD1 gene, which encodes myogenic differentiation 1. This protein is known to function in TNF-mediated cellular signaling pathways and muscle organ development, among other biological roles. The human version of PUM has a canonical amino acid length of 320 residues and a protein mass of 34.5 kilodaltons. It is reported to be localized in the nucleus of cells.
