- SynonymMucin-17,MUC-17,MUC17,MUC-3,MUC3
- SourceHuman MUC-17, His Tag (MU7-H52H3) is expressed from human 293 cells (HEK293). It contains AA Arg 4131 - Leu 4390 (Accession # Q685J3-1).Predicted N-terminus: Arg 4131 & 4244 SerRequest for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus. This protein was cleaved within the SEA domain between 4243 Gly and 4244 Ser, and was cleaved into N and C-terminal fragment with calculated MW of 12.6 kDa and 18.6 kDa respectively. The protein migrates as 20 kDa and 25-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>90% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human MUC-17, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
- BackgroundMembrane mucins have several functions in epithelial cells including cytoprotection, extravasation during metastases, maintenance of luminal structure, and signal transduction. MUC17, contains an extended, repetitive extracellular glycosylation domain and a carboxyl terminus with two EGF-like domains, a SEA module domain, a transmembrane domain, and a cytoplasmic domain with potential serine and tyrosine phosphorylation sites. Interacts via its C-terminus with PDZK1 and this interaction appears important for proper localization. Probably plays a role in maintaining homeostasis on mucosal surfaces.
