Recombinant human LACE1 (KIAA1343), a member of the aldehyde dehydrogenase (ALDH) superfamily, is a protein of growing interest in biochemical and biomedical research. LACE1. short for "lactation elevated 1." was initially identified for its elevated expression in mammary tissue during lactation. Structurally, it contains conserved ALDH catalytic domains, including NAD⁺-binding motifs and catalytic cysteine residues, suggesting potential enzymatic activity linked to retinoid metabolism. While its precise biological role remains under investigation, studies associate LACE1 with cellular processes like differentiation, proliferation, and apoptosis. Abnormal expression has been observed in cancers (e.g., breast, liver) and metabolic disorders, implying possible contributions to disease pathogenesis.
The recombinant form is typically produced in expression systems like E. coli or mammalian cells, enabling functional studies that native tissue-derived protein cannot easily achieve. Researchers use recombinant LACE1 to explore substrate specificity, enzymatic kinetics, and interactions with signaling molecules like retinoic acid derivatives. Its application spans disease mechanism studies, drug screening, and antibody production. Despite progress, challenges persist, including unresolved structural details (no crystal structure reported) and unclear endogenous substrates. Current work focuses on clarifying its redox-related functions and therapeutic potential in ALDH-associated pathologies.
