Gm364 Activators

Transmembrane 9 superfamily member 5 (TM9SF5) activators encompass a variety of chemical compounds that exert their effects by modulating distinct signaling pathways which subsequently influence the activity of TM9SF5. Forskolin, for example, stimulates the production of cAMP, a secondary messenger that activates PKA. The subsequent phosphorylation cascade can enhance the functional activity of TM9SF5 by modifying proteins within its associated pathways. Similarly, genistein indirectly increases the activity of certain tyrosine kinases which can lead to the phosphorylation and activation of proteins that are in the same signaling pathways as TM9SF5, enhancing its activity.

Inhibitors like LY294002, U73122, Gö6976, Chelerythrine, SB203580, PD98059, KN-93, Bisindolylmaleimide I, Okadaic acid, and Calyculin A, each affect different molecular targets within signaling networks, ultimately leading to the functional enhancement of TM9SF5. LY294002, through PI3K inhibition, can indirectly cause an increase in AKT activity, which may affect the trafficking and function of TM9SF5. Similarly, inhibitors of PLC, PKC, MEK, and CaMKII, such as U73122, Gö6976, Chelerythrine, SB203580, PD98059, KN-93, and Bisindolylmaleimide I, can create a cellular environment that compensates by activating alternative pathways or isoforms that interact with or enhance the function of TM9SF5. These alternative signaling events promote the functional activity of TM9SF5 by potentially increasing its phosphorylation state or influencing proteins that regulate TM9SF5 function. Moreover, the use of phosphatase inhibitors like Okadaic acid and Calyculin A underscores a strategy to enhance the activity of TM9SF5 by preventing dephosphorylation. These compounds sustain a heightened phosphorylation status within the cell, which can lead to the persistent activation of TM9SF5. By inhibiting protein phosphatases PP1 and PP2A, Okadaic acid and Calyculin A ensure that proteins within TM9SF5's signaling network remain phosphorylated, thereby supporting an enhanced functional state of TM9SF5.
