**Background of Recombinant Human RABL4 Protein**
The recombinant human RABL4 (RAB-like 4) protein belongs to the RAB family of small GTPases, which regulate intracellular vesicular trafficking and membrane dynamics. Unlike canonical RAB proteins, RABL4 lacks a conserved C-terminal lipid modification motif, suggesting distinct regulatory mechanisms. It shares structural homology with RAB-like GTPases involved in ciliary transport and cell division. RABL4 is implicated in primary cilia assembly and maintenance, potentially interacting with components of the intraflagellar transport (IFT) system to mediate cargo delivery.
Studies link RABL4 to cell cycle progression, particularly in S-phase entry, and its dysregulation may contribute to ciliopathies or cancer. Recombinant RABL4 is produced via bacterial or eukaryotic expression systems for structural and functional studies. Its purified form enables exploration of GTP-binding kinetics, effector interactions, and roles in ciliogenesis. Recent research highlights its potential as a biomarker or therapeutic target in cilia-related disorders, though its precise molecular mechanisms remain under investigation. Further characterization of recombinant RABL4 could clarify its contributions to cellular homeostasis and disease pathways.
