Anti-Dsk2 antibodies enable researchers to detect and measure the Dsk2 antigen in biological samples. This target is a reported synonym of the UBQLN1 gene, which encodes ubiquilin 1. This protein is known to function in the cellular response to hypoxia and autophagy pathways, among other biological roles. The human version of Dsk2 has a canonical amino acid length of 589 residues and a protein mass of 62.5 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, cytoplasmic vesicles, ER, and cytoplasm of cells and widely expressed in many tissue types.
