Anti-paralemmin antibodies are used in the immunodetection of the protein encoded by the PALM gene. In humans, the canonical protein has a reported length of 387 amino acid residues and a mass of 42.1 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be widely expressed with highest expression in the brain and testis and intermediate expression in heart and adrenal gland. A member of the Paralemmin protein family, it is known to be involved in plasma membrane dynamics and cell process formation. Other names for this target antigen include PALM1 and paralemmin-1.
