Biotinylated Human Mucin-1 (890-1158) Protein, His,Avitag™ (MALS verified)

Protein

RT

21.3 kDa (partial α chain) & 10.2 kDa (partial β chain)

Membrane 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.

Mucin-1

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag.
The mature form of Mucin-1 is a non-covalent heterodimeric complex with the proteolytically cleaved partial α and partial β chain. Each partial α and partial β chain has a calculated MW of 21.3 kDa (partial α chain) and 10.2 kDa (partial β chain).The protein migrates as 45-70 kDa (partial glycosylated α chain), 11 kDa and 14-15 kDa (partial glycosylated β chain) under reducing (R) condition (SDS-PAGE).
