Anti-A kinase (PRKA) anchor protein 11 antibodies enable researchers to detect and measure the A kinase (PRKA) anchor protein 11 antigen in biological samples. This target is a reported synonym of the AKAP11 gene, which encodes A-kinase anchoring protein 11. This protein is known to function in cytoskeleton organization and intracellular signal transduction, among other biological roles. The human version of A kinase (PRKA) anchor protein 11 has a canonical amino acid length of 1901 residues and a protein mass of 210.5 kilodaltons. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include AKAP220, PPP1R44, and PRKA11.
