Anti-podocan like 1 antibodies are used in the immunodetection of the protein encoded by the PODNL1 gene. In humans, the canonical protein has a reported length of 512 amino acid residues and a mass of 56.5 kDa. Its subcellular localization is in the extracellular matrix and is also secreted. Alternative splicing is reported to yield 3 different isoforms for this protein. The podocan like 1 protein is a member of the Small leucine-rich proteoglycan (SLRP) protein family. Post-translational modifications have been described, including N-glycosylation. Other names for this target antigen include podocan-like protein 1.
