[Isoform 1]: Cell membrane ; Peripheral membrane protein. Endoplasmic reticulum membrane ; Peripheral membrane protein. Microsome membrane ; Peripheral membrane protein. Mitochondrion membrane ; Peripheral membrane protein. Cell projection, neuron projection . Predominantly associates with endoplasmic reticulum membranes. Only a small fraction associates with mitochondrial and plasma membranes. .; [Isoform 2]: Mitochondrion inner membrane ; Peripheral membrane protein. Mitochondrion outer membrane ; Peripheral membrane protein. Lysosome lumen . 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.
