Anti-ASK3 antibodies enable researchers to detect and measure the ASK3 antigen in biological samples. This target is a reported synonym of the MAP3K15 gene, which encodes mitogen-activated protein kinase kinase kinase 15. This protein is known to function in protein phosphorylation, among other biological roles. The human version of ASK3 has a canonical amino acid length of 1313 residues and a protein mass of 147.4 kilodaltons, although 3 isoforms have been identified. ASK3 is a member of the STE Ser/Thr protein kinase protein family.
