WFIKKN2 recombinant protein is a biologically engineered molecule derived from the WFIKKN2 gene, which encodes a multidomain protein containing WAP, follistatin, immunoglobulin, Kunitz-type protease inhibitor, and netrin-like domains. This complex structure enables WFIKKN2 to interact with diverse molecular targets, particularly within extracellular matrices and signaling pathways. The protein is naturally expressed in multiple tissues, including the liver, kidneys, and nervous system, where it appears to regulate cellular processes such as adhesion, differentiation, and tissue remodeling.
Recombinant WFIKKN2 is typically produced using mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications. Its production enables detailed study of its functional domains and binding partners. Research suggests WFIKKN2 interacts with growth factors from the TGF-β superfamily and extracellular matrix components, potentially serving as a modulator of tissue repair mechanisms and inflammatory responses. Notably, its Kunitz domain exhibits serine protease inhibitory activity, hinting at regulatory roles in proteolytic cascades.
Current investigations focus on WFIKKN2's involvement in pathological conditions. Altered expression patterns have been observed in fibrotic diseases, cancer progression, and neurological disorders, positioning it as a potential therapeutic target or diagnostic biomarker. The recombinant form facilitates structural-function analysis through domain-specific mutagenesis studies. However, its complete physiological role remains incompletely characterized, with ongoing research aiming to clarify its dual roles in both promoting and inhibiting cellular processes depending on microenvironmental context. This bifunctional nature makes WFIKKN2 particularly interesting for developing context-dependent therapeutic strategies.
