== Disease == | |||
[https://www.uniprot.org/uniprot/MUC1_HUMAN MUC1_HUMAN] Note=MUC1/CA 15-3 is used as a serological clinical marker of breast cancer to monitor response to breast cancer treatment and disease recurrence (PubMed:20816948). Decreased levels over time may be indicative of a positive response to treatment. Conversely, increased levels may indicate disease progression. At an early stage disease, only 21% of patients exhibit high MUC1/CA 15-3 levels, that is why CA 15-3 is not a useful screening test. Most antibodies target the highly immunodominant core peptide domain of 20 amino acid (APDTRPAPGSTAPPAHGVTS) tandem repeats. Some antibodies recognize glycosylated epitopes. | |||
== Function == | |||
[https://www.uniprot.org/uniprot/MUC1_HUMAN MUC1_HUMAN] The alpha subunit has cell adhesive properties. Can act both as an adhesion and an anti-adhesion protein. May provide a protective layer on epithelial cells against bacterial and enzyme attack.<ref>PMID:9139698</ref> <ref>PMID:11877440</ref> <ref>PMID:14688481</ref> <ref>PMID:15710329</ref> <ref>PMID:16288032</ref> <ref>PMID:15513966</ref> <ref>PMID:17524503</ref> <ref>PMID:17308127</ref> <ref>PMID:16983337</ref> The beta subunit contains a C-terminal domain which is involved in cell signaling, through phosphorylations and protein-protein interactions. Modulates signaling in ERK, SRC and NF-kappa-B pathways. In activated T-cells, influences directly or indirectly the Ras/MAPK pathway. Promotes tumor progression. Regulates TP53-mediated transcription and determines cell fate in the genotoxic stress response. Binds, together with KLF4, the PE21 promoter element of TP53 and represses TP53 activity.<ref>PMID:9139698</ref> <ref>PMID:11877440</ref> <ref>PMID:14688481</ref> <ref>PMID:15710329</ref> <ref>PMID:16288032</ref> <ref>PMID:15513966</ref> <ref>PMID:17524503</ref> <ref>PMID:17308127</ref> <ref>PMID:16983337</ref> | |||
