AKR1D1

  • Official Full Name

    aldo-keto reductase family 1, member D1 (delta 4-3-ketosteroid-5-beta-reductase)

  • Overview

    The enzyme encoded by this gene is responsible for the catalysis of the 5-beta-reduction of bile acid intermediates and steroid hormones carrying a delta(4)-3-one structure. Deficiency of this enzyme may contribute to hepatic dysfunction. Three transcript variants encoding different isoforms have been found for this gene. Other variants may be present, but their full-length natures have not been determined yet.

While there is ongoing research on AKR1D1 as a potential drug target, it is still in the early stages. Scientists are exploring the development of AKR1D1 inhibitors for the treatment of bile acid-related disorders and investigating its role in other diseases. The potential therapeutic applications of AKR1D1 targeting are an active area of ongoing investigation.

Does AKR1D1 protein have any physiological or pharmacological inhibitors? 06/28/2021

There are currently no specific physiological or pharmacological inhibitors that are commonly used to directly target AKR1D1 protein. However, as mentioned earlier, some compounds have shown inhibitory effects on AKR1D1 activity in experimental studies. More research is needed to develop potent and specific inhibitors for therapeutic use.

How does AKR1D1 protein contribute to bile acid synthesis? 04/21/2021

AKR1D1 protein is a key enzyme involved in bile acid synthesis. It catalyzes the NADPH-dependent reduction of 5β-cholestane-3α,7α,12α-triol to 5β-cholestane-3α,7α,12α,24-tetrol, a key step in bile acid biosynthesis. This product is subsequently converted into primary bile acids, such as cholic acid and chenodeoxycholic acid. AKR1D1 is essential for the conversion of intermediates in the bile acid synthesis pathway and ensures the proper production of bile acids necessary for digestion and other physiological functions.

Are there any natural compounds or dietary factors that can modulate AKR1D1 protein activity? 12/01/2020

Some studies have suggested that certain natural compounds or dietary factors may influence AKR1D1 activity. For example, it has been reported that certain phytochemicals found in plants, such as curcumin and resveratrol, can modulate AKR1D1 expression or activity. Additionally, high fiber diets have been shown to increase AKR1D1 expression in animal models. However, the specific mechanisms by which these compounds or dietary factors affect AKR1D1 activity are still not fully understood and require further investigation.

Are there any known interactions of AKR1D1 protein with other proteins or enzymes? 09/29/2020

AKR1D1 protein is known to interact with other enzymes involved in bile acid synthesis, such as cytochrome P450 enzymes and 3β-hydroxysteroid dehydrogenase. These interactions are important for the sequential enzymatic reactions required for bile acid production. Additionally, AKR1D1 may interact with other proteins involved in cellular signaling or regulation, although the specific interactions are not well characterized.

Can AKR1D1 protein be targeted for the treatment of cholestasis or other liver diseases? 08/21/2020

Yes, targeting AKR1D1 protein could potentially be a therapeutic approach for the treatment of cholestasis and other liver diseases. AKR1D1 plays a key role in bile acid synthesis, and disruptions in bile acid metabolism are often associated with liver diseases such as cholestasis. By modulating AKR1D1 activity or expression, it may be possible to restore proper bile acid homeostasis and alleviate symptoms associated with liver dysfunction. However, more research is needed to fully understand the implications and potential of targeting AKR1D1 for liver disease treatment.

Does AKR1D1 protein have any isoforms? 02/14/2020

Yes, alternative splicing of the AKR1D1 gene can produce multiple isoforms of AKR1D1 protein, although the significance of these isoforms is not well understood.

Are there any inhibitors or activators of AKR1D1 protein currently in development? 12/20/2019

There have been a few studies exploring the development of AKR1D1 inhibitors as potential therapeutic agents for bile acid-related disorders. For example, the compound 3-O-β-D-glucopyranosyl-6-position-d-glucose has shown inhibitory effects on AKR1D1 activity. However, more research is needed to develop and evaluate these inhibitors for clinical use.

Can variations in the AKR1D1 gene affect drug response? 02/03/2018

It is possible that genetic variations in the AKR1D1 gene could impact drug response, particularly in medications that are metabolized by AKR1D1. However, more research is needed to understand the clinical significance of such variations and their effects on drug efficacy and toxicity.

Is AKR1D1 protein involved in any metabolic pathways besides bile acid synthesis? 10/03/2017

AKR1D1 protein plays a crucial role in the synthesis of primary and secondary bile acids, which are essential for lipid digestion and absorption. However, recent studies have also suggested potential involvement of AKR1D1 in other metabolic pathways, such as steroid hormone metabolism and xenobiotic detoxification. Further research is needed to fully understand these additional metabolic functions of AKR1D1.

Are there any known AKR1D1 protein polymorphisms or variants? 09/23/2017

Yes, several variants of the AKR1D1 gene have been identified in different populations. Some of these variants are associated with bile acid-related disorders, such as primary bile acid malabsorption (PBAM) and bile acid synthesis defects type 2 (BASD2). These genetic variations can affect AKR1D1 protein function and lead to impaired bile acid metabolism. Understanding these polymorphisms and variants is important for assessing individual susceptibility to bile acid-related disorders and optimizing personalized treatment strategies.

How is AKR1D1 protein regulated in the body? 05/26/2017

The regulation of AKR1D1 protein expression and activity is not fully understood. However, several factors have been shown to influence AKR1D1 expression. For example, feedback regulation by bile acids themselves can affect AKR1D1 expression levels. Transcriptional regulation by nuclear receptors, such as the farnesoid X receptor (FXR) and the pregnane X receptor (PXR), is also known to play a role in regulating AKR1D1 expression.

Other factors, such as hormonal signaling and dietary factors, can also influence AKR1D1 expression and activity.

Can AKR1D1 protein be used as a biomarker for certain diseases? 12/02/2016

While AKR1D1 protein itself is not commonly used as a biomarker, alterations in AKR1D1 activity or mutations in the AKR1D1 gene can be indicative of certain diseases, such as bile acid synthesis defects or potential metabolic disorders. Therefore, measuring AKR1D1 activity or analyzing AKR1D1 gene variants may have diagnostic value in specific contexts.
