The RIT (Ras-like without CAAX) family of proteins, which includes RIT1 and RIT2, is a subgroup of the Ras small GTPase superfamily. These proteins are unique within the Ras family due to the absence of a CAAX box at their C-terminus, which is typically involved in membrane attachment and post-translational modifications in other Ras proteins. RIT1 and RIT2 play significant roles in neuronal development, neuronal survival, and synaptic plasticity. They function as molecular switches, switching from a GTP-bound active state to a GDP-bound inactive state, thereby regulating several downstream signaling pathways. RIT proteins are involved in the activation of key signaling cascades, including the MAPK/ERK pathway, which is critical for cell growth, differentiation, and survival. Dysregulation of RIT signaling has been implicated in several disorders, including neurodevelopmental abnormalities and cancer, highlighting its importance in both normal cell function and disease.

Targeting RIT (Ras-like without CAAX) proteins for disruption or inhibition by small molecules is a valuable approach to unravel their mechanistic roles in cell signaling. By inhibiting RIT proteins, researchers can directly observe the effects on downstream signaling pathways, such as the MAPK/ERK pathway, which is critical for understanding their role in cell growth, differentiation, and survival. This approach allows them to analyze the specific contribution of RIT proteins to neuronal development and synaptic plasticity, areas in which they are particularly influential. Studying the effects of RIT inhibition may also shed light on the mechanisms underlying various neurodevelopmental disorders and some types of cancer, in which RIT signaling is implicated.
