N-琥珀酰基-5-氨基咪唑-4-羧酰胺5'-磷酸核糖是嘌呤代谢产物。 由于腺苷是神经元功能的有效抑制剂，可抑制几种兴奋递质的释放并引发神经元的直接过级化，因此腺苷琥珀酸裂合酶（ASase）缺乏症患者出现的症状可能反映了琥珀酰嘌呤对神经传递的干扰。
SAICAR 是嘌呤核苷酸从头合成的中间体，以同工酶选择性性方式激活 PKM2，EC50 为 0.3 mM。SAICAR 刺激 PKM2 并促进癌细胞在葡萄糖限制条件下的存活。|
Human Endogenous Metabolite

SAICAR accumulation induces nuclear localization of PKM2. PKM2-SAICAR phosphorylates and activates Erk1/2, which in turn sensitizes PKM2 for SAICAR binding through phosphorylation. Additionally, PKM2-SAICAR was necessary to induce sustained Erk1/2 activation and mitogen-induced cell proliferation. SAICAR-PKM2 interaction is necessary and sufficient to induce H3 T11 and Erk1/2 phosphorylation.
Upon glucose starvation, cellular SAICAR concentration increases in an oscillatory manner and stimulates PKM2 activity in cancer cells. The SAICAR-PKM2 interaction also promotes cancer cell survival in glucose-limited conditions. In glucose-limited conditions, cells with higher SAICAR concentrations (
adsl-kd
cells or cells overexpressing PAICS) survive better while
paics-kd
cells died earlier than control-kd cells. SAICAR promotes cancer cell survival in glucose-limited conditions.
