Additional notes
Previously labelled as IL3RA.
Molecular Mass: ab88358 migrates as a broad band between 85 and 100 kDa in SDS-PAGE due to post-translation modifications, in particular glycosylation. This compares with the unmodified protein that has a predicted molecular mass of 60.6 kDa.
ab88358 consists of 25-40% carbohydrate by weight. pI: ab88358 separates into a number of isoforms with a pI between 6.2 and 9.0 in 2D PAGE due to post-translational modifications, in particular glycosylation. This compares with the unmodified protein that has a predicted pI of 8.43. Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.

Stability and Storage
Shipped at 4°C. After reconstitution store at -20ºC. Avoid freeze / thaw cycles.
Constituents: 1% Human serum albumin, 10% Trehalose
-
ReconstitutionIt is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. Following reconstitution short-term storage at 4°C is recommended, and longer-term storage of aliquots at -18 to -20°C. Repeated freeze thawing is not recommended.

Function
This is a receptor for interleukin-3. -
Sequence similarities
Belongs to the type I cytokine receptor family. Type 5 subfamily. -
Domain
The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
The box 1 motif is required for JAK interaction and/or activation. -
Cellular localization

1D SDS-PAGE of ab88358 before and after treatment with glycosidases to remove oligosaccharides.
Lane 1: ab88358
Lane 2: ab88358 treated with PNGase F to remove potential N-linked glycans
Lane 3: ab88358 treated with a glycosidase cocktail to remove potential N- and O-linked glycans. Drop in MWt after treatment with PNGase F indicates presence of N-linked glycans. Subsequent drop in MWt after treatment with glycosidase cocktail indicates presence of O-linked glycans. Faint bands in lane 2 and lane 3 are glycosidase enzymes. -
A sample of ab88358 without carrier protein was reduced and alkylated and focused on a 3-10 IPG strip then run on a 4-20% Tris-HCl 2D gel. Spot train indicates presence of multiple isoforms of ab88358.
-
Densitometry of protein isoforms visualised by 2-DE.
The densitometry scan demonstrates the purified human cell expressed protein exists in multiple isoforms, which differ according to their level of post-translational modification.
The triangle indicates the theoretical MWt and pI of the protein.
