Peripheral membrane protein. Endoplasmic reticulum membrane {ECO:0000269|PubMed:15847605};
Peripheral membrane protein. Microsome membrane {ECO:0000269|PubMed:15847605};
Peripheral membrane protein. Mitochondrion membrane {ECO:0000269|PubMed:15847605, ECO:0000269|PubMed:19797320};
Peripheral membrane protein. Cell projection, neuron projection {ECO:0000250|UniProtKB:Q8BZL1}. Note=Predominantly associates with endoplasmic reticulum membranes. Only a small fraction associates with mitochondrial and plasma membranes. {ECO:0000269|PubMed:19797320, ECO:0000269|PubMed:21521691}.;
[Isoform 2]: Mitochondrion inner membrane {ECO:0000269|PubMed:15847605};
Peripheral membrane protein. Mitochondrion outer membrane {ECO:0000269|PubMed:15847605, ECO:0000269|PubMed:19797320};
Peripheral membrane protein. Lysosome lumen {ECO:0000269|PubMed:15213228}. Note=According to PubMed:15213228, isoform 2 is soluble, N-glycosylated and found in the lumen of lysosomes. However, no signal sequence nor N-glycosylation site is predicted from the sequence.
