**Background of Recombinant Human Ankyrin Repeat Domain-Containing Protein 45 (ANKRD45):**
ANKRD45 is a less-characterized member of the ankyrin repeat (ANK) protein family, which typically mediates protein-protein interactions essential for diverse cellular processes. Structurally, ANKRD45 contains multiple ANK repeats—conserved ~33-amino acid motifs forming tandem α-helical structures that facilitate binding to target molecules. While its precise biological functions remain under investigation, ANKRD45 is hypothesized to participate in signaling pathways, stress responses, and regulation of gene expression, similar to other ANK-containing proteins like IκB or ANKRD1.
Emerging studies suggest ANKRD45 may play roles in cancer progression and neurodegenerative disorders. For instance, aberrant ANKRD45 expression has been observed in certain tumors, potentially influencing cell proliferation or apoptosis. Its involvement in neurodevelopment is also speculated due to interactions with neural proteins, though mechanistic insights are limited. Recombinant ANKRD45. generated via heterologous expression systems (e.g., *E. coli* or mammalian cells), serves as a critical tool for functional studies, enabling exploration of its interactome, post-translational modifications, and pathway associations.
Current research focuses on elucidating ANKRD45's physiological and pathological relevance, leveraging *in vitro* and *in vivo* models. Deciphering its molecular mechanisms could unveil novel therapeutic targets for diseases linked to its dysregulation. However, comprehensive functional characterization remains pending, highlighting the need for further investigation.
