Recombinant human RAB40A protein belongs to the RAB family of small GTPases, which play pivotal roles in regulating intracellular membrane trafficking, vesicle formation, and cargo transport. RAB40A, a member of the RAB40 subfamily (including RAB40A, B, and C), is distinguished by a unique SOCS-box domain at its C-terminus, which facilitates interactions with components of the ubiquitin-proteasome system. This protein cycles between GTP-bound (active) and GDP-bound (inactive) states, acting as a molecular switch to coordinate membrane dynamics. RAB40A is implicated in modulating secretory pathways, endosomal sorting, and ciliogenesis, with emerging links to cellular processes like autophagy and cytoskeletal organization.
Studies suggest RAB40A may influence disease pathways, including cancer progression and neurodevelopmental disorders, though its precise mechanisms remain under investigation. Recombinant RAB40A is typically produced via bacterial or mammalian expression systems, enabling functional and structural studies. Its purified form aids in elucidating binding partners, GTPase activity assays, and roles in cellular signaling. As a research tool, it contributes to understanding RAB-mediated trafficking anomalies and potential therapeutic targeting. Further exploration of RAB40A's interplay with ubiquitination pathways and organelle-specific functions could uncover novel regulatory networks in cell biology.
