Anti-PKD1L1 antibodies are used in the immunodetection of the protein polycystin 1 like 1, transient receptor potential channel interacting. In humans, the canonical protein has a reported length of 2849 amino acid residues and a mass of 315.4 kDa. Its subcellular localization is in the cell projections. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis and in fetal and adult heart. A member of the Polycystin protein family, PKD1L1 is a known component of the ciliary calcium channel that controls calcium concentration within primary cilia without affecting cytoplasmic calcium concentration. Synonyms for this target antigen include PC1-like 1 protein, polycystic kidney disease 1 like 1, polycystin-1L1, and polycystic kidney disease protein 1-like 1. PKD1L1 gene orthologs have been reported in the mouse, rat, frog, zebrafish and chimpanzee species. A number of PKD1L1 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
