Ras-like protein family member 12 (RASL12)

Ras-like protein family member 12 (RASL12) is a small GTPase protein featuring a characteristic GTP-binding domain and GTPase activity[3][2][5]. It is predicted to participate in nucleotide cycling within the cell, exchanging GTP for GDP and potentially acting in signaling pathways, although its specific cellular and physiological roles remain unclear[4][2][6]. RASL12 lacks the lipid modification signals typical of many membrane-associated Ras superfamily members, suggesting it may function outside membrane compartments[4]. It has been implicated in rare gastrointestinal disorders (bile acid malabsorption and diarrhea), but no definitive disease mechanisms or pharmacological interactions are reported[6]. No current evidence supports its use as a drug target, biomarker, or risk factor. Note on ambiguity: RASL12’s functions and clinical relevance are poorly characterized compared to other Ras superfamily members. It is not currently considered a receptor, enzyme, or transporter, nor a validated drug target. Most information is predictive rather than experimentally confirmed.
