Anti-NIMA (never in mitosis gene a)-related kinase 5 antibodies enable researchers to detect and measure the NIMA (never in mitosis gene a)-related kinase 5 antigen in biological samples. This target is a reported synonym of the NEK5 gene, which encodes NIMA related kinase 5. This protein is known to function in protein phosphorylation, among other biological roles. The human version of NIMA (never in mitosis gene a)-related kinase 5 has a canonical amino acid length of 708 residues and a protein mass of 81.4 kilodaltons. It is reported to be notably expressed in the testis, nasopharynx, and fallopian tube. Other names for this target antigen include serine/threonine-protein kinase Nek5 and NIMA (never in mitosis gene a)-related kinase 5.
