Anti-LL5b antibodies enable researchers to detect and measure the LL5b antigen in biological samples. This target is a reported synonym of the PHLDB2 gene, which encodes pleckstrin homology like domain family B member 2. This protein is known to function in cell migration and cytoskeleton organization, among other biological roles. The human version of LL5b has a canonical amino acid length of 1253 residues and a protein mass of 142.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the membrane and cytoplasm of cells and widely expressed in many tissue types.
