PLEKHN1

Both PH domains are essential for its mitochondrial localization.

Controls the stability of the leptin mRNA harboring an AU-rich element (ARE) in its 3' UTR, in cooperation with the RNA stabilizer ELAVL1 (PubMed:29180010). Decreases the stability of the leptin mRNA by antagonizing the function of ELAVL1 by inducing its atypical recruitment from the nucleus to the cytosol (By similarity). Binds to cardiolipin (CL), phosphatidic acid (PA), phosphatidylinositol 4-phosphate (PtdIns(4)P) and phosphatidylserine (PS) (PubMed:18191643). Promotes apoptosis by enhancing BAX-BAK hetero-oligomerization via interaction with BID in colon cancer cells (By similarity) (PubMed:29531808).

Phosphorylation is essential for its mitochondrial localization and regulates its interaction with C1QBP.

Ubiquitous (PubMed:18191643). Epressed in several cancer cell lines of differing origin (PubMed:29531808).

• Cell membrane
• Lipid-anchor
• Mitochondrion
• Mitochondrion membrane
• Interaction with C1QBP and phosphorylation is essential for its mitochondrial localization. Localizes on the microtubule in the form of small granules.
