DESCRIPTION
Also known as CHP2_MOUSE, Chp2, Hca520. Functions as an integral cofactor in cell pH regulation by controlling plasma membrane-type Na(+)/H(+) exchange activity. Binds to and activates SLC9A1/NHE1 in a serum-independent manner, thus increasing pH and protecting cells from serum deprivation-induced death. Also plays a role in the regulation of cell proliferation and tumor growth by increasing the phosphatase activity of PPP3CA in a calcium-dependent manner. Activator of the calcineurin/NFAT signaling pathway. Involved in the cytoplasmic translocation of the transcription factor NFATC3 to the nucleus (By similarity). Interacts with PPP3CA. Interacts with SLC9A1/NHE1; the interaction occurs in a calcium-dependent manner. Interacts with SLC9A1/NHE1 (By similarity).
