    Summary
    Predicted to enable guanyl-nucleotide exchange factor activity. Involved in several processes, including mitotic nuclear membrane disassembly; negative regulation of axon extension involved in regeneration; and regulation of cell cycle process. Located in cell cortex; microtubule minus-end; and plasma membrane. Is expressed in U.la; U.lp; and linker cell. Orthologous to several human genes including PSD (pleckstrin and Sec7 domain containing). [provided by Alliance of Genome Resources, Apr 2022]

    What's a GeneRIF?
    1. It loss of EFA-6, a modulator of MT dynamics, can delay both neuronal aging and extend the lifespan of C. elegans.
      Title: Microtubule regulators act in the nervous system to modulate fat metabolism and longevity through DAF-16 in C. elegans.
    2. The EFA-6 N-terminus binds the microtubule-associated proteins TAC-1/Transforming-Acidic-Coiled-Coil, and ZYG-8/Doublecortin-Like-Kinase, both of which are required for regenerative growth cone formation, and which act downstream of EFA-6.

    3. C. elegans EFA-6 amino-terminus is both necessary and sufficient to limit microtubule growth along the cortex, and that this function is independent of ARF-6.
