Hypophosphatemia results from idiopathic renal phosphate loss.

CF is the most common genetic disease in the Caucasian population, with a prevalence of about 1 in 2'000 live births. Inheritance is autosomal recessive. CF is a common generalized disorder of exocrine gland function which impairs clearance of secretions in a variety of organs. It is characterized by the triad of chronic bronchopulmonary disease (with recurrent respiratory infections), pancreatic insufficiency (which leads to malabsorption and growth retardation) and elevated sweat electrolytes.<ref>PMID:1695717</ref> <ref>PMID:2236053</ref> <ref>PMID:1710600</ref> <ref>PMID:1284466</ref> <ref>PMID:1284468</ref> <ref>PMID:1284530</ref> <ref>PMID:1284529</ref> <ref>PMID:7680525</ref> <ref>PMID:7683628</ref> <ref>PMID:7683954</ref> <ref>PMID:7505694</ref> <ref>PMID:7504969</ref> <ref>PMID:7522211</ref> <ref>PMID:7513296</ref> <ref>PMID:7525450</ref> <ref>PMID:7520022</ref> <ref>PMID:7524913</ref> <ref>PMID:7524909</ref> <ref>PMID:7517264</ref> <ref>PMID:8081395</ref> <ref>PMID:7544319</ref> <ref>PMID:8522333</ref> <ref>PMID:7537150</ref> <ref>PMID:7541273</ref> <ref>PMID:7581407</ref> <ref>PMID:7543567</ref> <ref>PMID:7541510</ref> <ref>PMID:8800923</ref> <ref>PMID:8829633</ref> <ref>PMID:8723693</ref> <ref>PMID:8723695</ref> <ref>PMID:8956039</ref> <ref>PMID:9101301</ref> <ref>PMID:9222768</ref> <ref>PMID:9375855</ref> <ref>PMID:9401006</ref> <ref>PMID:9443874</ref> <ref>PMID:9521595</ref> <ref>PMID:9921909</ref> <ref>PMID:9736778</ref> <ref>PMID:9482579</ref> <ref>PMID:9554753</ref> <ref>PMID:9452048</ref> <ref>PMID:9452054</ref> <ref>PMID:9452073</ref> <ref>PMID:10094564</ref> Defects in CFTR are the cause of congenital bilateral absence of the vas deferens (CBAVD) [MIM:[https://omim.org/entry/277180 277180].

Necessary for recycling of internalized ADRB2. Was first known to play a role in the regulation of the activity and subcellular location of SLC9A3. Necessary for cAMP-mediated phosphorylation and inhibition of SLC9A3. May enhance Wnt signaling. May participate in HTR4 targeting to microvilli (By similarity).

== Publication Abstract from PubMed ==

Crystallization of recombinant proteins has been fundamental to our understanding of protein function, dysfunction, and molecular recognition. However, this information has often been gleaned under extremely nonphysiological protein, salt, and H(+) concentrations. Here, we describe the development of a robust Inka1-Box (iBox)-PAK4cat system that spontaneously crystallizes in several mammalian cell types. The semi-quantitative assay described here allows the measurement of in vivo protein-protein interactions using a novel GFP-linked reporter system that produces fluorescent readouts from protein crystals. We combined this assay with in vitro X-ray crystallography and molecular dynamics studies to characterize the molecular determinants of the interaction between the PDZ2 domain of Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (NHERF1) and cystic fibrosis transmembrane conductance regulator (CFTR), a protein complex pertinent to the genetic disease cystic fibrosis. These experiments revealed the crystal structure of the extended PDZ domain of NHERF1 and indicated, contrary to what has been previously reported, that residue selection at positions -1 and -3 of the PDZ-binding motif influences the affinity and specificity of the NHERF1 PDZ2-CFTR interaction. Our results suggest that this system could be utilized to screen additional protein-protein interactions, provided they can be accommodated within the spacious iBox-PAK4cat lattice.
