RANGAP1 a cytoplasmic GTPase activator for the Ras-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state. Antagonist of RCC1, a regulator molecule that keeps RAN in the active, GTP-bound state. RanGAP1 and RCC1 control RAN-dependent transport between the nucleus and cytoplasm. RanGAP1 is a key regulator of the RAN GTP/GDP cycle. Homodimerizes. Forms a tight complex in association with RANBP2 and the ubiquitin-conjugating enzyme E2 (UBC9).
