Background Information

INPP5E(72 kDa inositol polyphosphate 5-phosphatase) converts phosphatidylinositol 3,4,5-trisphosphate (PtdIns 3,4,5-P3) to PtdIns-P2.In mouse, highest protein expression was in brain, heart, and testis, with lower expression in thymus and lung, and very little expression in kidney, spleen, and liver(PMID:10764818). Defects in INPP5E are the cause of Joubert syndrome type 1 (JBTS1) and mental retardation-truncal obesity-retinal dystrophy-micropenis (MORMS)(PMID:19668215). It has 2 isoforms with the molecular mass of 66 kDa and 70 kDa.

INPP5E stained in FITC is compared to ARL13b in Cy3. Methanol fixation, Block 1h, incubate 2h with primary ab, and 1h with secondary ab. The antibody is still a bit noisy (despite the blocking at 5% and ab diluted in 2%BSA) but the signal is strong and match what we expect.
