Detailed summary for ISC1:

ISC1


Systematic name:
YER019W
Description:
Mitochondrial membrane localized inositol phosphosphingolipid phospholipase C, hydrolyzes complex sphingolipids to produce ceramide; activated by phosphatidylserine, cardiolipin, and phosphatidylglycerol; mediates Na+ and Li+ halotolerance
Related info:
Excessive iron causes YCA1-dependent cell death, presumably through a pathway in which cardioliping activates the neutral sphingomyelinase ISC1, which in turn generates ceramide
