Cell localization:[Processed inositol 1,4,5-triphosphate receptor associated 2]: Cytoplasm., Endoplasmic reticµLum membrane, Single-pass type IV membrane protein. Nucleus envelope. Cytoplasm, cytoskeleton, microtubµLe organizing center, centrosome. Cytoplasm, cytoskeleton, spindle pole. Chromosome. Note=Colocalized with ITPR3 on the endoplasmic reticµLum membrane...The protein encode dby this gene is expressed in a developmentally regµLated manner in lymphoid cell lines and tissues. The protein is localized to the cytoplasmic face of the endoplasmic reticµLum. [provided by RefSeq, JµL 2008]
