Contents

Function

Ras GTPase activating protein (RasGAP) inactivates Ras from its active GTP-bound form to its GDP-bound form[1]. It is part of the mitogenic signal transmission via its N-terminal SH2-SH3-SH2 domains.

Relevance

Inactivated RasGAP activate RAS which is mutated in 30% of cancer types[2]. RasGAP Colra1 is involved in infection-related morphogenesis in gourd family plants[3].
