Aldo-keto reductase family 1 member C-like 1 (AKR1CL1) is a poorly characterized member of the aldo-keto reductase (AKR) superfamily, a group of NADPH-dependent enzymes involved in metabolizing endogenous and exogenous substrates. Like other AKRs, AKR1CL1 likely adopts the conserved (α/β)8 barrel structure and exhibits oxidoreductase activity, though its precise catalytic function remains unclear. Phylogenetically, it clusters within the AKR1C subfamily, which primarily catalyzes the reduction of ketosteroids, prostaglandins, and xenobiotics. However, AKR1CL1 shares limited sequence homology with canonical AKR1C enzymes, suggesting divergent substrate specificity.
The gene encoding AKR1CL1 is expressed in various tissues, including the liver, prostate, and ovaries, implying potential roles in steroid hormone metabolism or detoxification pathways. Interestingly, AKR1CL1 expression appears upregulated in certain cancers, such as hepatocellular carcinoma, though its oncogenic or tumor-suppressive mechanisms are not yet defined. Unlike well-studied AKR1C isoforms (e.g., AKR1C1-4), AKR1CL1 lacks conserved catalytic residues critical for steroid hormone regulation, raising questions about its functional niche. Current hypotheses propose interactions with lipid-derived aldehydes or involvement in cellular stress responses. Despite structural predictions and tissue-specific expression patterns, AKR1CL1 remains an underinvestigated enzyme, warranting further biochemical and pathophysiological studies to elucidate its biological significance and potential therapeutic relevance.
