Mucin-1/MUC1 Protein, Human (Biotinylated, HEK293, His-Avi)

Mucin-1/MUC1 protein and its α subunit have dual functions of adhesion and anti-adhesion proteins, forming a protective layer on epithelial cells. At the same time, the β subunit and its C-terminal domain participate in cell signaling through phosphorylation and protein-protein interactions. Mucin-1/MUC1 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived Mucin-1/MUC1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

The Mucin-1/MUC1 protein exhibits diverse functional roles: the alpha subunit possesses cell adhesive properties and functions as both an adhesion and an anti-adhesion protein, potentially forming a protective layer on epithelial cells against bacterial and enzyme attacks. Simultaneously, the beta subunit, with its C-terminal domain, engages in cell signaling through phosphorylations and protein-protein interactions. Mucin-1/MUC1 modulates signaling in ERK, SRC, and NF-kappa-B pathways, influencing the Ras/MAPK pathway in activated T-cells. Additionally, it plays a role in promoting tumor progression, regulating TP53-mediated transcription, and determining cell fate in the genotoxic stress response. Notably, in conjunction with KLF4, Mucin-1/MUC1 binds to the PE21 promoter element of TP53, thereby repressing TP53 activity and contributing to the intricate network of cellular functions.

Measured by its binging ability in a functional ELISA. Immobilized Human MUC1 at 2 μg/mL on streptavidin coated plates can bind Anti-MUC1 antibody. The EC₅₀ is 2.332-4.052 ng/mL.
