    217 amino acids
    Molecular mass:
    24668 Da
    Quaternary structure:
    • Interacts with AFDN, the C-terminal domain of RALGDS and RLF, but not with RIN1 and PIK3CA. RLF binds exclusively to the active GTP-bound form (By similarity). Binds calmodulin. Interacts with PLXNB3. Interacts with POU4F1 (via N-terminus); the interaction controls POU4F1 transactivation activity on some neuronal target genes (By similarity).
    • Shows rapid uncatalyzed guanine nucleotide dissociation rates, which are much faster than those of most Ras subfamily members.
