Descripción

General description

Polycystin-1 (UniProt P98161; also known as Autosomal dominant polycystic kidney disease 1 protein) is encoded by the PKD1 gene (Gene ID 5310) in human. The primary cilium is a microtubule-based mechano- and chemo-sensory organelle that coordinates an array of cellular pathways during development and in tissue homeostasis, including Hedgehog (Hh), PDGFRα and Wnt signaling. Defective ciliary function causes a variety of ciliopathies, including autosomal dominant polycystic kidney disease (ADPKD). Polycystin-1 (PC1) and polycystin-2 (PC2) are large transmembrane proteins co-localized to primary cilium, where they play an important role in calcium-based signalling. PC1 is an atypical adhesion G-protein-coupled receptor (aGPCR) with 11-transmemrbane domains. PC1 is cis-autoproteolytically cleaved at a juxtamembrane GPCR cleavage site (GPS; a.a. 3012-3061) in a developmental stage-dependent manner, where PC1 is largely uncleaved in early embryonic kidneys but becomes extensively cleaved after birth. GPS cleavage results in a heterodimeric PC1 form, in which the N-terminal fragment (NTF) remains non-covalently associated with the transmembrane C-terminal fragment (CTF). Transgenic mice expressing non-cleavable PC1 develop cystic kidney disease during the postnatal period.

Specificity

Clone E4 (also known as clone 5F4D2) targets polycystin-1 extracellular C-type lectin domain and immunostained wild-type, but not Pkd1-knockout murine cells (Kim, H., et al. (2014). Nat. Commun. 5:5482).

Immunogen

Epitope: C-type lectin domain.

FLAG-tagged recombinant human polycystin-1 C-type lectin domain.

Immunohistochemistry Analysis: An 1:50 dilution of this antibody from a representative lot detected polycystin-1 immunoreactivity in rat and mouse kidney tissue sections.
Immunoprecipitation Analysis: A representative lot immunoprecipitated polycystin-1 from mouse lung tissue lysates (Courtesy of Dr. Feng Qian, University of Maryland School of Medicine, Baltimore, MD).
Western Blotting Analysis: A representative lot detected exogenously expressed polycystin-1 in lysates from HEK cells transfected with human or mouse Pkd1 cDNA, but not in lysates from mock-transfected HEK cells (Courtesy of Dr. Feng Qian, University of Maryland School of Medicine, Baltimore, MD).
Western Blotting Analysis: A representative lot detected the polycystin-1 (PC1) GPS domain cis-autocleaved N-terminal fragment (NTF) in lysates from HEK cells transfected with full-length Pkd1 cDNA, but not in lysates from mock-transfected HEK cells (Kim, H., et al. (2014). Nat. Commun. 5:5482).
Immunocytochemistry Analysis: A representative lot and an anti-Arl13b antibody co-stained the primary cilium of 4% formaldehyde-fixed, 0.1% Triton X-100-permeabilized murine embryonic fibrolasts (mMEF) and collecting duct (CD)-derived cells by dual fluorescence immunocytochemistry. No polycystin-1 immunoreactivity was detected in Pkd1-knockout mMEFs (Kim, H., et al. (2014). Nat. Commun. 5:5482).
