    Article Title: Small GTPase ActIvitY ANalyzing (SAIYAN) system: A method to detect GTPase activation in living cells.
    Article Snippet: Small GTPases are essential in various cellular signaling pathways, and detecting their activation within living cells is crucial for understanding cellular processes.. The current methods for detecting GTPase activation using fluorescent proteins rely on the interaction between the GTPase and its effector.. Consequently, these methods are not applicable to factors, such as Sar1, where the effector also functions as a GTPase-activating protein.

    Loss of functional Sar1 GTPase inhibits ER NKCC2 export. ( A , B ) representative immunoblot showing the effect of overexpressing WT Sar1 or its dominant negative (DN Sar1) Sar1 H79G on NKCC2 processing.

Middle panel, the same membrane stained with Ponceau S to illustrate the equal loading of protein extracts. Lower panel, Representative immunoblot illustrating the expression of endogenous Sar1 (control) and transfected WT Sar1 and its dominant negative in HEK cells.

    JNK and p38 are involved in TGF-β1-induced Sar1a expression. HTSF were cultured in 6-well plates, serum-starved for 16 h, and then treated with or without 10 ng/mL TGF-β1, TGF-β1 + 10 μM JNK inhibitor (SP600125), 50 μM ERK inhibitor (PD98059), or TGF-β1 + 10 μM p38 inhibitor (SB203580) for 24 h. The cell culture supernatant was collected for PC-I ELISA (c, f, and i), and cell lysates were immunoblotted with antibodies against the indicated proteins (a, d, and g).
