Human Transmembrane protein 55B (TMEM55B) ELISA Kit,Abbkine,KTE60277
• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination. • Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.

Scientific Background
TMEM55B catalyzes the degradation of phosphatidylinositol 4,5-bisphosphate (PtdIns-4,5-P2) by removing the 4-phosphate. The deduced 257-amino acid protein contains a central Cx(5)R phosphatase catalytic motif and 2 transmembrane domains near its C terminus, a characteristic of lysosomal transmembrane proteins. RNA dot blot analysis detected expression in all tissues examined. Fluorescence-tagged TMEM55B localized with membrane markers of late endosomes or lysosomes. Endogenous HeLa cell TMEM55B showed a similar distribution.It showed no activity toward other phosphatidylinositol substrates or inositol phosphates tested. Overexpression of TMEM55B in human embryonic kidney cells reduced the total cellular level of PtdIns-4,5-P2.
