Recombinant human KLHL32 protein is a genetically engineered form of the Kelch-like protein 32. encoded by the KLHL32 gene. KLHL32 belongs to the Kelch-like family, characterized by a conserved BTB (BROAD-TRANTRACK-BRIC-A-BRAC) domain, a BACK (BTB and C-terminal Kelch) domain, and multiple Kelch repeat motifs. These structural features enable interactions with cullin-RING E3 ubiquitin ligase complexes, suggesting a role in substrate recognition for ubiquitination and proteasomal degradation. While its precise biological functions remain understudied, KLHL32 is hypothesized to regulate cellular processes like cytoskeletal organization, stress response, or cell cycle progression through targeted protein degradation.
Research on KLHL32 has been limited compared to other Kelch-like proteins, but emerging studies link it to disease pathways. For example, KLHL32 mRNA is differentially expressed in certain cancers and neurological disorders, implying potential involvement in tumor suppression or neurodegeneration. Recombinant KLHL32 is typically expressed in bacterial or mammalian systems for in vitro studies, enabling biochemical assays (e.g., protein-protein interaction analyses) and functional exploration of its ubiquitin ligase activity. Its production facilitates investigations into substrate identification and regulatory mechanisms. Despite progress, challenges persist in delineating its physiological substrates and tissue-specific roles. Further studies leveraging recombinant KLHL32 could clarify its contributions to cellular homeostasis and disease pathogenesis.
