XPLN Activators

Chemicals classified as XPLN activators encompass a diverse array of molecules that can indirectly influence the activity of XPLN by modulating pathways and processes related to Rho GTPase signaling. The activity of Rho GTPases, the direct targets of XPLN's GEF activity, is tightly regulated by numerous factors including their phosphorylation status, their interaction with the actin cytoskeleton, and the activity of downstream signaling components.

Some chemicals such as PMA, Calyculin A, and Okadaic acid can potentially modulate the activity of XPLN by affecting the phosphorylation status of proteins involved in Rho GTPase regulation. Others, namely Jasplakinolide, Latrunculin A, and Cytochalasin D, indirectly influence XPLN activity by affecting the state of the actin cytoskeleton, a key element in Rho GTPase signaling. Lastly, molecules such as Y-27632, Fasudil, H1152, NSC23766, EHT 1864, and ZCL278 can indirectly modulate the GEF activity of XPLN by inhibiting Rho GTPases themselves or their downstream effectors, thereby changing the overall dynamics of Rho GTPase signaling.
