**Background of Recombinant Human FLJ22405 Protein**
Recombinant human FLJ22405 protein, also known as IQ motif-containing GTPase-activating protein 3 (IQGAP3), is a cytoskeletal regulator encoded by the *IQGAP3* gene. It belongs to the IQGAP family, characterized by conserved structural domains including a calponin homology domain (CHD), an IQ motif for calmodulin binding, and a Ras-GAP C-terminal domain. FLJ22405 plays a critical role in cell cycle regulation, particularly during cytokinesis and mitosis, by interacting with components of the actin cytoskeleton, microtubules, and signaling molecules like Rac1/Cdc42. Its activity is crucial for maintaining cell polarity, adhesion, and spindle positioning during division.
Studies highlight its overexpression in cancers, such as hepatocellular carcinoma and colorectal cancer, where it promotes tumor cell proliferation, migration, and invasion by dysregulating Wnt/β-catenin and MAPK pathways. Recombinant FLJ22405 is typically produced in *E. coli* or mammalian systems, purified via affinity chromatography, and utilized for functional assays, antibody development, and mechanistic studies. Research continues to explore its potential as a diagnostic biomarker or therapeutic target in malignancies and disorders linked to aberrant cell cycle dynamics.
