== Disease ==
[https://www.uniprot.org/uniprot/RENI_HUMAN RENI_HUMAN] Defects in REN are a cause of renal tubular dysgenesis (RTD) [MIM:[https://omim.org/entry/267430 267430]. RTD is an autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype).<ref>PMID:16116425</ref>   Defects in REN are the cause of familial juvenile hyperuricemic nephropathy type 2 (HNFJ2) [MIM:[https://omim.org/entry/613092 613092]. It is a renal disease characterized by juvenile onset of hyperuricemia, slowly progressive renal failure and anemia.<ref>PMID:19664745</ref> 
== Function ==
[https://www.uniprot.org/uniprot/RENI_HUMAN RENI_HUMAN] Renin is a highly specific endopeptidase, whose only known function is to generate angiotensin I from angiotensinogen in the plasma, initiating a cascade of reactions that produce an elevation of blood pressure and increased sodium retention by the kidney.

== Publication Abstract from PubMed ==
A systematic investigation of the S3 sub-pocket activity requirements was conducted. It was observed that linear and sterically small side chain substituents are preferred in the S3 sub-pocket for optimal renin inhibition. Polar groups in the S3-sub-pocket were not well tolerated and caused a reduction in renin inhibitory activity. Further, compounds with clog P's &lt; or = 3 demonstrated a dramatic reduction in CYP3A4 inhibitory activity.
